Hey guys I just bought a Dell Dimension E520 and upgraded it as much as I could but the graphics card options were not the best. I got a NVIDIA GeForce 7300 LE at 256MB and I definitely need to upgrade. I play games like Empire at War and Command and Conquer and want to run them on full graphics. Right now they are running in the mid range. I am a big gamer but not really familiar with the technical side of it all. It has a dual core processor at 2.13GH and 4GB of RAM. It also has Vista. I really don't want to spend more than $350-$400 either. Any suggestions would be much appreciated!
