The i3 is pretty weak, I'd just spend a bit more money for an i5 760 lynnfield, and the 4 cores would be better for video editing and gaming.

For a graphics card, I'd also instead of spending like 300 USD for 2 HD 5770's I'd spen about another 80 USD and go for an HD5870. LAter on, you could set up eyefinity, which would could help with video editing and work, also, it would make gaming A bit more fun, and your current pick of Power supply would still be enough for the stronger processor and graphics card.

If you would like some good cooling for your processor, the Corsair H70 just came out, which would keep that pretty cool, though, the Corsair H50 might be good enough to keep your processor nice and cool.

The Noctua NH-D14 will keep anything cool, but, you will need a rather large case for that, and, since it is so large, It might hit your RAM if it is tall enough.

There is also the Antec KUHLER Box and the Coolermaster V8 if you want a normal sized Processor cooler. It can be very hard to pick a processor cooler, there are just so many to pick from.

This is what i wrote earlier

socket LGA1156 was a big fail. The new LGA1155 coming out in end of this year so LGA1156 is no worth to buy. When new socket is out there are no new CPUs coming in LGA1156 socket.
And of cource LGA1156 CPUs cannot install to LGA1155 socket.
And the reason for all this:
LGA1156-based solutions weakness is the DMI bus, which corresponds to a custom PCI Express 1.1 x4 bus.
The ability to transfer a 1 GB / s in both directions. A similar problem as AMD has, but the big difference LGA1156-based solutions is just one of the chipset. This means that all PCI-Express lines, which the processor is not performing, consume bandwidth for this transfer.
In practice, the current DMI bus to prevent a very effective Serial ATA 6 GB / s, USB 3.0, etc. recovery techniques, unless it is done at the expense of the graphics card performance. And this is not what "gamers" want.
DMI bus is so bad scalability bottleneck, thinking that it alone is enough to make LGA1156-based solutions in the near future in terms of completely unusable.

I keep forgeting about that, but, the i3 is kinds weak, he could go for A Phenom II X4 and be better off.

hmmm, i may wait a little extra till next year for the 1155 platform to be launched, suprised i missed that to be honest, and intel's light peak.

and as for the graphics cards i said the two 5770's in crossfire because, well, they perform better than a 5870 and are quite abit cheaper. but then again the 6000 series cards could be out by the time the new 1155 platform is out soo...

also the noctua NH-d14 sounds good to me, will be fitting into an extended form factor case anyhow so should be plenty of space.

You could also wait until the 6000 series comes out, and then buy 2 5870's because their prices would drop significantly.
