I hope you are going to have more than just G2 to run on that computer. I have a 1.6 ghz athlon, 256 meg ddr, and a 64 meg g-force 2 that I run it with and it runs outstanding. That is an awful lot of money for a video card. Please tell me that is a 128 meg card. What I am trying to say is that it doesn't take near the computer that you are thinking about to run this program with no problems. You could save a lot of money in the way of the video card and the processor that you could use for good hobbies like rc planes and helis. Well anyway if you go with what you're thinking you should be happy.
