Weeks worth of research and my build almost complete! Please advise

You might look at getting a modular power supply. Corsair, Seasonic and Silverstone have good ones.

the money you save there
you can put into a 120 GB SSD instead

60 GB fills up fast

Hey,

Thanks for the tip! I've looked into what you've said extensively looking into reviews and benchmarks and the performance is a matter of a few fps's between the 570 and 580. When you're getting 60+ fps in games on the 570 then I don't see why I would want a few more here and there which I wouldn't notice.

I am going to buy a 570, probably the MSI DirectUII if I plan on overclocking or the EVGA Superclocked. The latter has 25mhz more than the stock 580 (EVGA 570 has 797mhz, stock 580 has 772). I can then further overclock this if I want.

I may as well buy the 570 and save $259 dollars here or £160.00 here in England!! With the spare money I will buy a Hyper 212 and better power supply as test tube and crazyhorsejohnny advised.

I am unsure as to how much power I need now... I may go GTX 570 SLI and I may overclock my GPU and CPU. How much power do I really need? If it's 800w+ then it will cost a fortune in electricity bills and I was under the impression that the i5 at stock would not bottleneck with latest games.

Make sure you get an 80+ certified power supply. If you can find one at a price you are comfortable with, go with an 80+ silver or gold. Power supplies only draw what power they need, the more efficient it is the less power it needs to pull from the wall. Excess power is converted into heat, so there will be less heat given off as well.
