Just so you know. For the AMD build, you picked a AM3 mobo which uses DDR3 and you picked DDR2 ram and an AM2 cpu.
You can use an AM3 cpu on an AM2/AM2+ mobo but not the other way around. Switch the mobo to a DDR2 one, or get a Phenom II X3 720 BE and some DDR3 ram.
THe X3 720 is better than the E8500, but I personally like Intel better. Although the AM3 socket has a future and the 775 is done. So either get i7 or AM3 imo.
