Im looking at playing counter strike and doom3, stuff like that. Im guessing that $500 is american. If i got the asus motherboard with the 3800+ X2, corsair 512mb ram, a decent power supply and a cheap 128 or 256mb graphics card would it be able to hande a fully modded gta sa. If i do that i will get a better graphics card when can afford it. Is there any thing im forgetting? i already have a case and moniter.
