Gaming spec for £700

[InQ]

My bro's looking for a PC for gaming, budget is £700 but he doesnt need a monitor, kb or mouse (so case and guts plus speakers).

What can you do?

OK sorry about not getting back guys....but good news, more money to spend.
He tells me he has some PC3200 OCZ RAM from his old P4 setup that he's going to use in the new system plus he's just got an OEM Opteron 146 (for £113) from elsewhere so he doesnt need a CPU....so that now makes it a budget of £600 for case and guts (bar RAM and CPU) and speakers.
Of course he's going to be clocking the Opty...

Drop the CPU and RAM from my spec and your down to under £600 and should be able to clock the opty decently enough. That mobo is the same one used in the OCuk clocked rig and also the one I use. If you can fit it in the budget you can of course go for a DFI Lanparty but I'm happy in the Asus and it does have a good set of overclocking options.

Two things though - 1) the PC3200 IS DDR isn't it? Not DDR2. 2) is it a matched pair of ram to get dual channel?

Cheers, yep its a matched pair of DDR NOT DDR2 (P4 3GHz Northwood, Asus P4P800E Deluxe mobo).
I have mentioned he could get the same mobo as me (DFI Ultra-D) but he has looked at a cheaper DFI...
DFI NF4 Infinity SKT939 nForce4 chipset Dual DDR400 PCI-E SATA ATX
The Ultra-D uses the NF4 Ultra chipset and this Infinity uses the NF4 chipset (SATA not SATA2, dont know of any other significant differences?).
