So the new computer is fully up and running. I'd like to say thanks to everyone who gave me advice here as it helped quite a lot.
Some quick pics I took (excuse the shoddy cable management, this is to be sorted!):
Full specs:
Case: CoolerMaster XB
PSU: Antec 750W semi-modular
CPU: i5 3570k OC'd to 4.6 Ghz
Cooler: Alpenföhn K2 Mount Doom (Yes, its HUGE)
Mobo: Gigabyte G1 Sniper M3 M-ATX
RAM: 16GB TeamGroup ddr3 (2x 8GB)
GPU's: 2X 3GB EVGA 660 GTX SC edition
All hooked up to my 1080p HDTV.
I've done a few tests/benchmarks with it over the last few days and I'm really pleased with the performence. Huge step up from my Phenom 965 and GTX 480 (oh the noise that thing made...). This setup is so much quieter and cooler than my previous. My CPU is sitting around 28 degrees idle and the highest I've seen under load while gaiming is 56 degrees. This cooler is amazing and the amount of air in the XB case is really helping. The GPU's are hitting max 60 degrees and the fans never get higher than 40%. So all in all this is looking to be a cool and quiet setup while offering blistering performance.
The GPU's have laughed at everything I've thrown at them. They are just powering through everything. High IQ settings, downsampling, nothing is making them sweat. I will post some benchmarks later but this is a quick one just to give you an idea of how they are performing:

I've had no microstutter issues or driver issues so far with anything I've tried. Its all been smooth as butter. I guess SLI has come a long way compared to complaints people were having a few years back. For the £360 I've sent on the GPU's, I've got 3GB of VRAM and performence that more than beats any single card setup that I could have got for the same money. I
think I may be ready for Crysis 3!
Benchmarks to follow later today.
