As a computer tech, I am no fan of what I call the alternate windows versions. XP is still quite buggy in and of itself. And there will be manufacturer/hardware/driver wars for a while yet. If you have a few spare bucks (and the space), you might go over to eBay and purchase a system to dedicate to just your Tradestation trading. Make sure the operating system is Windows 98 (second edition). Just using this platform for your trading operations should help with the resource hogging issues. The Matrox drivers are more developed and stable in this setup. I have some clients with Matrox cards and as good as they are they can be problem prone sometimes. You should be able to cure this trouble for a few hundred bucks.
