Asus L1N64-SLI WS Dual L (1207 FX)

[pseudocajun]

Hi, I currently have a Abit KN8 Ultra mobo and an AMD 4600 cpu. I'd like to keep my box and upgrade the mobo, cpu, and memory. Any thoughts on installing the Asus L1N64-SLI WS into my tower with 2 64 FX-74 cpu's. As I understand, sometime next year, the 4x4 quad processors will be out and the two dual cores can be replaced with the two quad core into this board, correct.

Also, I still use XP and I assume this board works with XP even though it is 'certified for windows vista?'

thanks in advance for any assistance,
