I'm just about to update my PC and I'm wondering what is the best components to choose. I've heard alot of talk about holding out until next year, which I assume is because of DX10. Surely the DX10 will be directly related to graphics cards and not motherboards as such or am I incorrect?. Anyway here are some of the components I'm thinking about buying. ASUSTEK AM2 nForce 570 SLi ATX (not sure wether to buy the 939 socket AN8-Sli. What's the difference as I kow you can get dual core 939 chips) Not sure about a Am2 chip though. If I go for the 939 socket I was thinking about getting the AMD 64 4600+ dual core 512kb. Geforce 7900 GT 512 MD DDR3 PCI 2BG 184 pin PC3200 RAM Any suggestions or help would be greatly appreciated as I'm planning to spend about £700 - £800 inlcuding a new case/PSU/DVD rewriter etc.
