Right, so here's what I came up with so far:
Cpu Intel Q6600 (£115) or E8500 (£125)
Gpu Nvidia 9800GTX+ (£130)
Ram OCZ DDR2-800 ReaperX 4GB (£70)
Mobo Asus P5Q pro (£84)
Heatsink Arctic Cooling Freezer 7 Pro (£13)
Psu Hiper 630W (£54)
Hdd Samsung Spinpoint F1 500GB (£43)
Dvd Optiarc (Sony/NEC) AD-7201S-0B (£17)
Case Hiper Osiris (£80)
Monitor Samsung SM223BW (£163)
Kb Logitech G11 (£38)
mouse
Speakers
A few notes:
Cpu - With the recent intel price cuts suggesting that e8500 should be cheaper, I would go for that one. But at the moment it's not the case, so I'll stick with q6600
9800GTX+ should perform quite well, and I prefer Nvidia that little bit more
Case - I really like the look of Hiper Osiris, and it seems to get good reviews.
Keyboard - someone recommended Logitech G11 as a great gaming kb; but since I also do a lot of text typing/editing, I need something that feels comfortable. Any suggestions?
Mouse and speakers - have no idea at the moment, but I need something comfortable for gaming, and I like my music at good quality
At the moment it's around £806, without the mouse, speakers, OS (I can get an XP Pro for free on MS academic licence, but only 32 bit) and delivery (some of those items are from ebuyer, which offers free delivery). I'm looking at up to £900ish budget, maybe a grand if I can get 0% finance options
So how does that look?
