New gaming rig need input/advice please

Hi all, gonna get down to building a new gaming rig (mainly play fps like crysis/farcry 2 etc) and just wanted some opinions on my choices and whether anyone would change anything, my last build was an evga 680i+8800gtx combination(Tom's H forums also helped me out loads with selecting the build and it has been almost flawless and so here i am again) , so its been a while and im a little rusty on my knowledge of current components, combos etc hehe.

Any help would be greatly appreciated, im very open to all opinions.
Il be ordering everything from ocuk which limits which brands are available on certain parts

so....

CPU: Intel Core i7 920 D0 Stepping (SLBEJ) 2.66Ghz

CPU COOLER: Prolimatech Megahalems Performance CPU Cooler

MOBO: Gigabyte EX58-UD5 Intel X58 Motherboard

RAM: Corsair XMS3 6GB (3x2GB) DDR3 PC3-12800C7

GPU: Sapphire ATI Radeon HD 5870 1024MB GDDR5 PCI-Express Graphics Card (SINGLE card not crossfire)
(really an nvidia guy and just might wait for their next card which is suppost to be coming soon but from my understanding this is king at the moment)

HDD: Samsung SpinPoint F3 1TB

PSU : Corsair TX 950W ATX

I will probably add another 5870 (crossfire) after a while when my wallet gets fat again but for now one will do

I game on a dell ultrasharp 3007wfp so i need the right set up to game in 2560x1600

I will also be doing some overclocking (trying for 4ghz but probably leaving it at 3.8, that is if i even manage although my chosen cooler should do the trick)

choosing the mobo and ram was the hardest part, and i chose the gigabyte since ocuk offer it as a bundle with the corsair ram and corsair cooler, i am unsure whether this is the best choice but i like the fact that the ra is 6gb and really cheap so as long as it wont hurt my gaming too much and its quality ram il be fine.

Well, thats all i wanted to say so what do you guys think? any input is highly appreciated

^ That is a good setup...and as for the mobo and RAM, they are very good and Gigabyte boards are know for their stability during overclocking...

But I would suggest a different HDD - Get the WD Black 640GB or the Samsung F3 500GB/ Seagate 7200.12 500GB drives...they are newer and faster...

And for HD 5870 crossifre, you wont need 910W PSU...
Instead get a modular 750W/ 850W PSU from Corsair/ Silverstone/ Seasonic/ PCP&S/ OCZ gold series...

and as for the psu's u mentioned, the one i stated is cheaper than all of them ;/ so is the pcp&c 910w more powerful than them?

do you mean http://www.overclockers.co.uk/show [...] ubcat=1084 ? as far as i can see its still not modular and only 20£ cheaper

dunno for 20£ i think il stick with the pcp&c but thanks alot anyway, what about the ram, do you think its a good choice or will i get more out of games with a more expensive choice(reasonable odcourse)

hmm what about:

OCZ Gold 6GB (3x2GB) DDR3 PC3-12800C8 (1600MHz)

oh and btw whats the current best cpu paste atm or best few?

thanks loads for your input gkay!! changed a few parts again if u wanna take a look hehe, think its prety much perfect now except that i cant decide on a good case ;/

i really like the CM cosmos rc-1100 S "sport", looks big enough and really nice too, any comments on that?
