Suggested Microprocessor to avoid bottlenecking

[T-Rex]

Hey guys, I'm currently building an Alienware M17x, and I'm going with a single 2GB NVIDIA GTX 580M video card ( http://www.geforce.com/#/Hardware/GPUs/geforce-gtx-580m/specifications ). In light of that, is the Intel i7 2630QM microprocessor ( http://ark.intel.com/Product.aspx?id=52219 ) good enough to avoid cpu bottlenecking? There's also the 2720QM and the 2820QM offered for this laptop, but I don't know if I need them at all. I am completely lost here, I have no idea how to measure this, any help would be greatly appreciated!

Use the standard 2630qm cpu. The 2820qm is only 300 hertz faster; not worth what they would charge for the upgrade.

How about the 2720? It's also a difference of 300 but for $150 extra instead of $390~

If you're aren't worried about the cost, go for it. The 2720 looks like the best bang for the buck you can get, only 100 hertz slower than the 2820. For $150 extra, it's a better deal.
