Whats a better processor?

[vwboosted]

O ok.... because I have two diff computer one has a p4 and other the amd sempron. But the one with the amd sempron has a internal graphics card which works pretty good and 4 slots for ram the other only has two. Ill just stick with the one with the amd sempron. I just started it up and got it working and it had about 65fps with almost all settings maxed on lfs. So that should work on for him. He got cancer real bad and cant work so i figured something he can play games on and web surf would be a good gift. Thanks much.
