Sub Total: £780.12Plus I will be purchasing 2 60 GB solid state drives and running them in Raid, is that beneficial?With regards to graphics card, any reason why I should buy a better one than what's listed above?I look forward to your feedback.Regards,Mohawk200x

700W PSU? I think that's maybe a bit too low. I'd go minimum 800W, but only a gold 90% efficient 800W. Using inboard raid? Don't bother. Kills FSX performance. Go ahead if your using a raid card. Why such an old case? Nine Hundred has been out for a few years now. Get something with more room/better cooling, like the 902,1200 HAF X etc. Get the i7 950. PCs a touch easier and is only a tiny bit more expensive. 2000MHz isn't needed. I'd get 1600MHz 6-8-6-24 ram instead. Like the mushkin radioactive or mushkin redline.
