Need Feedback on a Laptop Build

[Rukentuts]

Any sort of feedback would be appreciated.

CPU: 3rd Generation Intel® Core™ i7-3610QM (6MB Cache, up to 3.3GHz w/ Turbo Boost 2.0)
RAM: 12GB Dual Channel DDR3 at 1600MHz (4DIMMS)
GPU: 2GB GDDR5 NVIDIA® GeForce® GTX 680M
Screen: 17.3-inch WideFHD 1920 x 1080 120Hz

Questions in particular: Would the bottleneck of this system be the CPU or GPU? Would this particular GPU call for the 120Hz screen, or would it produce FPS close enough to 60 on ultra that it really wouldn't matter?

Thanks in advance.

There will be no bottleneck there. It's more than apt for gaming and that resolution (for a notebook), but the RAM is more than a bit overkill.

Yeah, I'm still weighing the 60Hz vs 120Hz screens though >_<

[BicycleMafioso]

Get the 60Hz version. You will likely have the oomph to run it 120 Hz even in games, but at more reduced settings. I'd rather not do that trade-off personally.
So go with price.

Also, the obligatory statement; You will always get more for your money with a desktop.
