I am a gamer and I just bought an Intel(before you start, I didnt know much about AMD, so i foolishly got an intel) Pentium 4 3.2 ghz w/HT and 1 GB of RAM, 1 mb L2 cache and a 6200 TurboCache graphics card. I am hoping I am hoping to play next-gen games on it like Unreal Tournament 2007 and Oblivion. If I upgrade my graphics to an X1800XT 512 mb and 2 GB RAM, will I be able to play next-gen with good FPS and medium-high settings?
