depends. You see there is ALWAYS a bottleneck in your system, something will be the slowest part no matter what. So the i3 will often be a bottleneck, though you won't notice it because your fps will be really high so it doesn't matter much... but to give you an example of some titles where the i3 will bottleneck you... any game that's seriously threaded... like crysis 3 or battlefield 4. those games like "MOAR CORZ!"...
