I was wondering would an i3 3220 cause a bottleneck in using a Radeon HD 7870 or HD 7850. I am have an old HD 6870 but the last time I used it it was crashing in any game after an hour at stock speeds, and think the i3 3220 is an underated CPU. If the 7870 is too much for this CPU, just mention something else noteworthy......but i would like to make use of the pci-e 3.0....
