Re: 64 bit v sempron
Yeah, the sempron is an old generation card. The amd 3200+ amd 64 is definitely the newer, better, faster cpu. The amd's feature a built-in on-die controller, which puts it ahead in games. You don't have to upgrade though.... the slowing problem could just be an insufficent amount of ram. HOwever, with 1gb of ram, it's probably your cpu. The amd 3200+ 64 is an excellent and I totally recommend you get it. Make sure it's socket 939 though, so you can upgrade to the dual cores when they come out.
