Has i have said before it's more down to what you are trying to run as to whether or not the GPU or the CPU is the contributing Bottleneck. Don't get to hung up on bottlenecking. Just try the games and monitor your CPU/GPU usage with programs such as MSI Afterburner/EVGA Precision and watch what percentage of you GPU is being used.
If let's say you are playing ArmA II and you notice only 50% of your GPU being used. That signifies that your CPU is holding it back. Basically you want to be seeing somewhere in the 90%+ region of your GPU being utilized. But on the other hand Arma II is very much CPU dependent and not that well optimized in all fairness.
For instance on my old system with a Q6600@3.2GHz and a GTX 560 i would see around 50 - 60% GPU usage. Now on my i7 email@example.comGHz and the same GTX 560 i see 99% GPU usage more or less constantly.
So yea. Don't worry to much about bottlenecks. Just try the games and if they aren't running to well then back off some settings etc.
