The Video Card

Well, I've been an NVidia fan for years, and I really thought I'd go for the new NVidia 6800 Ultra.  They've got fantastically stable drivers, dual monitor support, and dual DVI support.  However, it's US$600 and I've got a wife - she'd never go for it.  :)  So, the other option, as was wisely discussed in the comments of my previous post on the subject, is an ATI Radeon 256Meg 9800 Pro.  It's roughly US$299 (half the price) and arguably comparable results for my needs.  Sure, it won't do 100fps but who needs to? 

I wanted Dual-DVI but I'm not willing to pay for it.  There are a few options, but the ATI 9800 Pro is a good compromise.  ONE of it's outputs is DVI, the other is Analog.  So, I run the Dell FP2001 off the DVI at 1600x1200x32 and the Viewsonic VA800 off analog at 1280x1024x32.  It's a very good compromise.  Add in the Tablet PC with Maxivista running at 1400x1080 and that's ~4.7million pixels working for me.

The other reason is that there's an active an happy overclocking community around this card.  The drivers and the card are stable and I've been able to get +11% FPS in most games by overclocking it from 378Mhz(core)/337Mhz(mem) to ~418Mhz/357Mhz.  I can take it higher, but a few artifacts creep in.

Ordinarily I'm not big on overclocking, but in my research I discovered RadLinker, an amazing and free utility for ATI Radeon-based cards.

From his site:

RadLinker is new tweaker/linker for ATI Radeon based graphics cards.  RadLinker features:

• Absolutely no programs running in the background
• Does not bloat the registry
• Per game/program settings
• Control over process priority
• Per game/program clock rate settings
• As many unique game profiles as your computer can hold
• Custom profiles for all your games

RadLinker allows you to create a "RadLink", a special kind of shell link (a.k.a. shortcut) to your games/programs that allows you to change it's individual settings.  A RadLink will look and act just like a normal shortcut except it's property settings can be custom tailored for your video settings.

RadLinker adds a tab to your Display Properties, but also lets you make custom shortcuts for each game.  In these shortcuts you can specify not only all the details like AntiAliasing, Texture Quality, etc, but the overclocking settings for your Video Card just for that game!  What a fantastic idea.  It works great, and I've been running FarCry and Dungeon Siege at 1600x1200x32 with 4x Anti-Aliasing on and getting 25-30fps!  The difference is NIGHT AND DAY from my NVidia FX5200.  The only problem I've had is with BattleField 1942, apparently there's a problem with the video on Radeons, and I've been unable to get past the menu. 

The Processor

I've also had some trouble with my little P4-3Ghz overheating when rendering DVD Video, squishing TV-Video into WMV or playing games for long periods. 

After toying with the idea over water cooling, I talked to Richard Campbell (an expert on the subject) and decided that was over-kill.  So, I picked up a Zalman CNPS7000A-Cu and installed it.  It was breeze, literally and figuratively.  My average temp is around 42°C and it doesn't get to more than 55-58°C when it's REALLY working.  The case and harddrive are usually around 37°C. 

It also included a Fanmate so I run the Zalman at <2000RPM with the two case fans around 2200RPM.  Currently the loudest thing in the room is the 400W Power Supply fan.  Over all, it's doing OK, and I'm very pleased with the quieter and cooler operation, as well as the stellar 3D and Dual Monitor Support.

This fan also included a free component called "Cooling After" that runs the fans in your computer for a some number of minutes (I set mine to three minutes) after it's turned off.  This is to avoid the sudden spike in temperature that happens after a hot machines shuts off and the fans stop.  It blinks the power-light to let you know it's still cooling down your system.  A nice little piece of insurance.  Kind of like when your car's engine fan continues even after you turn it off.

The Tools/Software

I'm using the following programs to manage all this:

• RadLinker for ATI Radeon-based cards.  A MUST HAVE.  It's free, but I paypaled the guy $10 just on principle.
• MBM5 Motherboard Monitor.  Tells you the temperature of the CPU, the other temp monitors on your MB, the RPM of the Fans, and other neat stuff.  The first and the best.  (Sadly Alex Van Kaam, the author, has decided to stop development on MBM as of today, July 6th, 2004.  It's a shame, but 7.5 years on one program is a long time.  Good luck to him!) 
• DTEMP Hard Drive Temperature Meter - Great little tray icon that not only tells you the temperature of your hard drive (assuming it's a newer one with this ability) but it also monitors the S.M.A.R.T. details and MTBF metrics.
• SpeedFan.  Programmatically control the speed of your system's fan(s).  This is great if you'd like to get the quietest system possible, while still running the fans at a decent speed.

Thanks again to everyone who helped me with all this, and for the ATI 9800 Pro suggestion - also running an LCD with DVI versus Analog really is noticeable, especially when the native resolution of the LCD Is 1600x1200.

Notice the average score (the green arrows)...is it just me, or if the AVERAGE is 40% on a test, maybe there's something wrong with the test? (or I'm an idiot. ;) One of those.)  Gee, I hope my boss doesn't read my blog, or take tests for that matter.  Well, it only took 15 minutes.

This was the Introduction to .NET for Developers: Microsoft Visual C#® .NET, I got the link from Bryant.

I'm amazed that anyone's computer still runs anymore!

This holiday weekend, when you (computer person) visit your cousin/dad/aunt/grandma, give them a gift:

* install anti-spyware software and configure it to run automatically on startup. I use SpyBot Search and Destroy.
* enable their existing Windows Xp firewall, just turn it on
* give them anti-Virus software (or install the free version of AVG)
* run diskcleanup and defrag
* lower the size of the IE cache
* turn the security in IE up (for ActiveX controls) or install FireFox.

Let's make July 4th a Safe To Surf Day!

A friend of mine sent me some code just now where he was experimenting with Close and Dispose on SqlConnection.  Reflectoring into SqlConnection shows it closes open connections in Dispose().  So, here's the before and after code.  I think it shows good examples on why the using statement exists, and when to avoid (hide) superfluous try/catches.  I also changed a few nits for readability by using certain overloaded constructors as well as String.Format().

BEFORE - The code I was given:

private void RunScriptOnDB(string filename,string DB)
{
    SqlConnection sqlcon = new SqlConnection();
    sqlcon.ConnectionString ="Persist Security Info=False;Integrated Security=SSPI;Initial Catalog="+DB+";Data Source=(local);";
    SqlCommand com = new SqlCommand();
    com.Connection = sqlcon;
    try
    {
        StreamReader sr = Utility.GetStreamOfFile(filename);
        com.CommandText = sr.ReadToEnd();
        sr.Close();
    }
    catch(FileNotFoundException fileex)
    {
        msg.Text = fileex.Message;
        return;
    }
    try
    {
        sqlcon.Open();
        com.ExecuteNonQuery();
        msg.Text = "Successful";
    }
    catch( SqlException sqlex)
    {
        msg.Text = sqlex.Message;
    }
    finally
    {
        if(closingMethod.SelectedValue == "c") //SDH: He's trying different closing methods based on a Radio Button, this won't be needed in a refactor
        {
            sqlcon.Close();
        }
        else if(closingMethod.SelectedValue == "d")
        {
            sqlcon.Dispose();
        }
        else
        {
            sqlcon.Close();
            sqlcon.Dispose();
        }
    }
}

AFTER - My quickie refactor/clean:

private void RunScriptOnDB(string filename, string database)
{
   string commandText = String.Empty;
   try
   {
      using (StreamReader sr = Utility.GetStreamOfFile(filename))
      {
         commandText = sr.ReadToEnd();
      }
   }
   catch (FileNotFoundException fileEx)
   {
      msg.Text = fileEx.Message;
      return;
   }
   using (SqlConnection connection = new SqlConnection(String.Format("Persist Security Info=False;Integrated Security=SSPI;Initial Catalog={0};Data Source=(local);",database))
   {
      using (SqlCommand command = new SqlCommand(commandText, connection))
      {
         try
         {
            connection.Open();
            command.ExecuteNonQuery();
            msg.Text = "Successful";
         }
         catch (SqlException sqlEx)
         {
            msg.Text = sqlEx.Message;
         }
      }
   }
}

Remember all the weirdness around Collections and VB6 when VB.NET came out?  I just noticed this breaking change as we move from 1.1 to Whidbey.  Previously added workaround code will have to be removed.

VB collections have weird implementation of IList: 0 based for read and -1 based for insertion
Affected APIs none: Ilist implementation of VB collection is fixed
Affected Assemblies\Dll(s): Microsoft.VisualBasic.dll
Affected Scenarios: Upgraded apps that use VB Collection through inconsistent implementation of Ilist (very unlikely scenario) may be broken.
Description: An instance of Collection type is casted to Ilist and then used via Ilist interface. To make this work in 7.0, 7.1 you would need to specialcase access to Ilist if it holds Collection
Workaround Code that has special-case warkarounds to use Collections casted to Ilist, will have to remove workarounds.
