Looking good, I7 is a beast and you might want to overclock it up to 4.0 ghz just like mine, extra power always come in handy if you like to push those settings high.
Also go 6gb RAM with triple channel.
I have Radeon HD 5850 and does the job incredibly well, running bad company 2 1920 x 1080 at high smoothly. Also its about 30 bucks cheaper than GTX 460.
If you do go overclocking though, I recommend a specilized case with very good airflow, fans with manual switch are great.
Take a look at this spec: http://www.overclockers.co.uk/showproduct.php?prodid=FS-101-OE

XFX Double dissipation Radeon HD 7950 356 bit 3gb GDDR5 OC @ 1150 MHz core + 1575 x 4 memory
Triple channel DDR 3 12gb RAM 1600 MHz
