Hello guys, just built a new system last night to replace my old bakup computer. Its a sempron 2800(overclocked to 1.8 ghz) 128 mb 5200,1gb memory, 100gb hard drive, 4x dvd burner, on a km800 motherboard. It replace my athlon xp 2200, and athlon m 1ghz(overclocked to 1.333 ghz) backup systems. I have so much more space now. The sempron chips are great and cheap. As it stands I now have only three pcs, X2 4200. sempron 2800, and core duo notebook. My newphew is the proud owner of the 2200, which now has a radeon 9600xt instead of geforce 440, and it has 1gb og memory instead of 512, the other system is boxed up for later disposal.
