Best performance for under $1000?

Someone on another forum was looking for a PC to replace his laptop, and was wanting to build a
gaming PC anywhere between $600-$1000 including OS. No resolutions above 1080P, no 3D, and no multiple monitors.
He wants the PC to be able to play new games for around 1-2 years without having to upgrade the GPU. Not looking to play BF3 as far as I know.

So how is this build?

The two parts I am most unsure about is the 560ti and the motherboard.
Motherboard seems a little pricey, but it does include PCI-E 3, which might help in the long run.
The video card is also questionable. A 7850 seems to run more efficient and cooler than a 560ti, right?
He doesn't want to buy and then instantly have the price drop it seems, so he is contemplating putting the build off till June.


Opinions?
