I know the i5 and i7 doesn't really make a difference for gaming but the gtx 670 should blow the gtx 650ti out of the water and that still doesn't explain why the spec with the 650ti could run starcraft 2 on ultra better. Both build has the same spec with the only thing being different is the graphic card.
On cyberpower the build with the gtx 650ti 2gb runs starcraft 2 on ultra at 87 fps while the spec with the superior gtx 670 2gb only runs it at 81 fps. Both resolutions are at 1920x1200.
If anyone knows why, please let me know, thanks in advance!
