First time build - any suggestions?

I'm looking to buy a PC that is capable of running all games maxed out (with exceptions to Crysis - but I would like it playable )

I've had a go but I'm not sure what it's like etc.

Anyway this is what I came up with:

Tuniq Tower 120-LFB CPU Cooler (Socket 478/754/939/940/AM2/LGA775)
(£35.24)

Intel Core 2 Quad Q9300 LGA775 'Yorkfield' 2.50GHz 6MB-cache (1333FSB) Processor - Retail
(£184.46)

Antec Nine Hundred Ultimate Gaming Case
(£70.49)

Logitech G11 Gaming-Grade Illuminated Keyboard - Retail (967929-0120)
(£38.76)

Logitech MX518 Gaming-Grade Optical Mouse - Retail
(£27.01)

Samsung SM-2232BW Pebble 22" Widescreen LCD Monitor - Glossy Black
(£223.24)


What would be the best graphics card for me to get with this screen resolution? (1680x1050)
What mobo would go best with this setup as I am looking for something that I can use in the future, perhaps for SLi but not essentially for that?
What PSU would I need to run this, and also I want to be ale to be used in the future, say if I add another card a later date?

Or can anyone build me a good system for me, my price range is about £1200, about $2400 but I would prefer not to spend the whole amount.



Thanks in advance

coo, thanks for the info on mobo's - i will take a look into them. How much of a performance increase will there be (roughly) with SLi'ing 2 GTS' (G92)? And Can I still overclock my CPU with the 780i board?

what about 2 8800 GT's in SLi, i've looked at some benchmarks and it performs quite well at the 22" resolution.
