Want to upgrade to a quad and am thinking of the Q9550 overclocked to 3ghz.Here is what I currently have (taken from DXDIAG) : Operating System: Windows XP Professional x64 Edition (5.2, Build 3790) Service Pack 2 (3790.srv03_sp2_gdr.080813-1204) System Manufacturer: Gigabyte Technology Co., Ltd. System Model: P35C-DS3R Processor: Intel® Core2 Duo CPU E6850 @ 3.00GHz (2 CPUs), ~3.0GHz Card name: NVIDIA GeForce 8800 GTX Memory: 4 Gig Crucial Ballistix DDR2 800Am thinking of a complete I7 upgrade but would rather not splash out all that cash yet. thanksGraham

that rig should be doing you pretty well at the moment. but a q9550 will give you smoother gameplay and maybe allow you to play at higher settings, but i would say save up for a full rig, not just the CPU. The core 2 quads are on middle ground now, quite good performance for the price, but with more i7/i5 etc releases soon, it doesnt seem like an upgrade that will last, Philip

Cool, thanks for the replies.I overclocked my E6850 from 3ghz to 3.6ghz with a thermal take cooler last night. It runs quite well and temps dont go > 57C when running Orthos for few hours.Am thinking of changing this to the Q9550 this weekend hopefully overclocking to 3.6ghz which should run quite well then with the 4 cores.The E6850 can stay in a drawer for a few weeks on its own til I buy another motherboard, ram etc then I can build another PC and network it via WideView.regardsGraham
