Here is my system build so far: 

HAF 912+ Midi Tower Case (High Air Flow)
2 x 200mm Coolermaster Megaflow Fans (Front & Top)
1 x 120mm Case Fan (Rear)
1 x 140mm Case Fan (Side)
Intel iSeries i7 930 Processor (Plan to OC to 4.2GHz)
Coolermaster V6GT CPU Cooler 
Gigabyte GA-X58-UD3R Motherboard
Corsair TX650W PSU

So my plan at the end of the month is to get 2 x Western Digital 'Caviar Black' 1TB hard drives and put them in RAID 0. I am also looking at getting either the Dominator GT 2000MHz Ram or some ram of equal speed and quality and either a LG DVD/RW or Sony DVD/RW. Now my problem lies in what graphics card to get, I've had a look at a lot of benchmarks, videos and forums and from what I can gather the best bang for buck is the GTX 460 768MB version in SLi, BUT, I am worried that my PSU may not be able to handle the SLi, SO, I have also been looking at the Sapphire AMD ATi Radeon HD5870 'Vapor-X' Card. I am fully open to suggestions and my budget for the graphics card(s) is between £250 and £350 any suggestions would be greatly appreciated.

Used and with 2 GTX 460's and a 4.2ghz overclock you're looking at 550-600w. This all depends on the CPU vcore. I calculated with it at 1.35v which should be doable.

However your power supply is not on Nvidia's list for SLIing two GTX 460's.

I like the ASUS GTX570 that I just got. No need for SLI at all. It runs things without problems and is priced at about $350.00 for one that's slightly overclocked. Your Power Supply would handle it without problems too.

Dogs are great judges of character, and if your dog doesn't like somebody being around, you shouldn't trust them.

I like Neil's suggestion. It also gives you more room for upgrading in the future as it can to tri-sli, vs just the 2x Sli with the 460.
