Ok this my current config: I have a Core 2 Quad Processor running on Intel DP35DP. HD-320gb 7200rpm Sata. My current video card is Nvidia 7600gs. I want to go for an upgrade. I also dont want to go for the best graphics card but dont want to find out that due to my rest config im not able to get the max out of it. Guys what would be the best graphics card for my current config??
