I`m looking to upgrade my current system (xp2800+, Asus a7n8x deluxe, radeon 9700pro) and am after some advice. I`m going for a system based on the AMD 64 4000+ and I`ve some questions regarding the mobo / Graphics. I was going for an Asus A8N SLI mobo and either an 850 xt pe radeon or a pair of 6800 GT or ultras (depending on the price). It`s going to be water cooled to keep it as quiet as possible (it runs constantly in a bedroom) The memory is my current Corsair 3200 LL twinX matched. Any advice would be nice.
