If I only want to upgrade one thing (other than RAM), what should it be, CPU or GPU? Upgrading to dual core would mean a new MOBO, my current one is Asus A8N SLI deluxe, so a new GPU would be cheaper than new MOBO/CPU, but I'm not sure what would give the best increase in performance.
Do all MOBOs support Nvidia and ATI graphics cards and is there any point in multiple GPU card slots? I've never used the SLI on my current MOBO as it means having to buy two cards at once. Buying a 6600GT 128mb a couple of years ago and then adding another identical card now wouldn't make much difference, would it? So I'm dubious about the value of SLI and its cousins.
All I want is a system that can run Crysis/Bioshock and beyond at reasonable settings (doesn't have to be maximum).
Also, while you can't get the full benefit of DX10 cards without Vista, will they run on XP without any problems (compatibility and performance-wise?)
One other thing: I've been told to avoid cases with built in PSUs. Is this good advice?
Anyone got any suggestions?

Asus EN8800GTS 640MB DDR3 PCI Express £222. If I splashed out on this, how long would it likely be 'future proof'?
Thanks for any help!
