Delivery from Overclockers.co.uk I'm stuck on to build the above or to simply upgrade to a 7800GS and wait for Conroe/Vista to roll out before jumping in a years time? I'm into heavy gaming, F.E.A.R, Dreamfall:TLJ, PoP:T2T, (Especially)OBlivion , HL2 ETC - I also do alot of multitasking, loads of background programs running. So better off upgrading to 7800GS and wait or start building the system above and wait another 3 years? Suggessions appreciated. Edit: I'm a student, £1500 is from (intensive) summer jobbing. Also, I have system at 1280x1024 on normal but game at 1024x768 (max, usually).
