so you want a computer + monitor + mouse + keyboard + speakers for 600£?
well... are you buying from overclockers.co.uk (recommended by me)?
gonna post some links here later
600£ is a bit tight, but it might work if offc you build it yourself and you don't expect
top-of-the-line performance.
EDIT: take a look at this system:

i know, over budget. this will destroy anything you throw at it though...
GPU: you could go with the 4850, that's your call.
i went with very basic speakers, but they perform very well. i have them at home too. if you have more room you could go with a 5.1 system, but i bought one too and all 5 speakers are sitting in front of me. again, this is your call.
mouse and keyboard: this is a matter of taste, but the G11 is great. that mouse will suffice for guild wars or any other game.
monitor: 22'', because of the budget. samsung makes great quality monitors though
PSU: it's enough for one 4870, but if you wanna go cfx, then you'd better upgrade to minimum 700w
optical drive: well, don't waste money here. anything, and i mean anything, will do here.
hard drive: samsung spinpoint = quality. 500gb will suffice i think, but if you want you can upgrade to 1 TB.
case: well, here i had to think of the budget again. if you don't like the looks of that case, choose another one, but i'd stick with antec. they just build quality cases.
motherboard + ram + cpu: again, i had to think of the budget. take another cpu if you want, but amd = more bang for the buck. if it's just gaming you wanna do, then i wouldn't recommend quad core with your budget. mobo and ram have same socket and should work.
hope this was helpful
