Agreed with staffsmike, £190 on 2 gig of DDR is seriously expensive, especially when the cheaper stuff (read 3 to 4% slower only) is about £70! (or even under £45 for 2 gig that'll get the job done, not that i'm advocating it, just demonstrating the price).
The 8800GTS 640MB will be great, even for 1920 x 1200 (thought you said you didnt want widescreen!).3) 2Gb RAM is my minimum, I'd like 4 if possible. What do I use it for? Video Encoding, 3D animation, large spreadsheets, graphics, and gaming.
