I have an older system that im currently using that i got at a yardsale. It has a amd 3800+ 64 bit and 1gb ram and onboard video. The question I had was. If i upgraded my memory to 4gb which is capacity, and the video card to a geforce gtx 550 ti. If this system would still be good for games. I think i remember 3800+ is equivilant to around 3.2 ghz, i know its not a dual core but I was wanting some opinions
