I'm sorry for my pointless reply but i just can't help and be pissed off at how computer parts are so much cheaper in the USA then UK... I bought the i5 2500k for £176, which equals about 270$, Oh and that was the cheapest i could find it too.
Graphics card same deal, $285 in USA, £225 in the Uk for a cheaper brand, saphire was £240.
Anyway, to add some point to this post, i agree with the above post (joel) on the parts, + If it still works you can bios flash the 6950 into a 6970 for extra performance.
For gaming 4 GB of ram should be enough, and if you ever need more, you can always add another set of 2x2gb Sticks.
Haven't seen anywhere of people posting that the bios flash doesn't work, but i do remember reading somewhere that ATI might update their new supplies of 6950's to disable it, Oh and it is worthwhile to mention that even if the graphic card is capable of doing it, it doesn't always work out but as far as i've read if it doesn't work out, you just reset it and no permenant damage done to the video card.
Overall, the graphics frame rate performance has the AMD Radeon HD 6970 matched nicely to the GeForce GTX 570. Measured at stock (reference) speeds in ten different tests, the Radeon HD 6970 was either slightly ahead in half of them or deeply trailed in the other half. We've excluded HAWX 2 from this review, until AMD drivers can compensate for the performance skew. The DirectX 10 tests seemed to really score the GeForce GTX 570 way ahead, while many of the DirectX 11 tests pulled the Radeon HD 6970 ahead by a few FPS:
3DMark Vantage has the 6970 ahead by 2.9% (1680x1050) or 5.8% (1920x1200) on the Jane Nash test, but then sinks 16.9/9.4% for New Calico. Crysis Warhead pushed the GTX 570 16.2/9.4% ahead, but then DX11 Aliens vs Predator pushed back 10.4/12.3% in favor of the Radeon HD 6970. Shader intensive games such as Battlefield Bad Company 2 really strained the Radeon HD 6970, giving the GTX 570 a 31.9/25.3% lead. BattleForge did the same, giving the GTX 570 a 53.5/57.1% lead over the 6970. Lost Planet 2 dog-piled also the results in favor the GTX 570, resulting in a 45.1/41.9% lead over the 6970. Then, thankfully, the Radeon HD 6970 fought back in NVIDIA-strong games like Mafia II, producing a 0.9/6.0% lead over the GTX 570. Metro 2033 gave the 6970 a 3.1/5.2% edge, and then the Heaven 2.1 benchmark offered a 2.0/7.5% difference in favor of the 6970.
