You on XP or Vista? As if you on XP didn't think it could handle 4gb of ram, only 3 and if your on DDR2 3 would be usless? And also instead of buying the 8800gtx would be better of waiting till the new nivda cards thats are coming out soon, thinks its January time don't quote me on that though. Even then you would need to SLI them up to get it out.
