Hi, I have been looking for a graphics card for my computer to run Sims 3. Right now I have a Nividia Geforce 9400GT. I have windows 7 professional SP1. Intel Pentuim 4 cpu 3.2 Ghz 3192 Mhz, 1 Core, 1 Logical Processor. The computer is a Dell Dimension E310. I also put a 400 wt power supply in the computer. Can anyone help me. I have looked at alot of cards but I am not a computer geek. Thanks in advance.
