Hello, my name is Mike. I am currently in the process of trying to find the proper graphic card to run Warhammer on my older Compaq S6500NX Tower. Original specs: http://www.shopping.com/xPF-Compaq-COMPAQ-S6500NX-Presario-Desktop-Computer ...My tower has a Athlon 3000+ 2.167Ghz Processor; equivalent to ~3Ghz Pentium 4. And it has 333Mhz Bus Speed...I have been recommended by Can You Run It's website to get any of these cards: (Nvidia - FX 5900, 6600-6800, 7600+ / ATI Radeon - 9500-9800, X300-X850, X1300+ / Intel - X4500) ...I am wondering if anyone has any experience with any of these cards and has any preference? I am also wondering, depending on the card, what (Size, Brand, Wattage) Power Supply I will need to replace my current 250W, and will I need any Cooling Fans, etc... I have also upgraded my original 512mb memory to 2Gb, and I had to change out my original top DVD E-Drive to a HP One: http://www.bestbuy.com/site/olspage.jsp?skuId=8346827&st=dvd+drive&lp=5&type=product&cp=1&id=1176506511356 ...Please let me know if you need any other information. Any help will be greatly appreciated. Thanks.
