GTX 760 not working as well as GTX 560TI?

A friend of mine recently built his own computer and has been having issues with his graphics card performing poorly.

He has a Gigabyte GTX 760 with 2GB DDR5 along with other new components. However, he has been unable to run his games at any setting higher than low and even then its a bit shaky.

On the other hand, I have a mid-end computer I built 2 and a half years ago with a EVGA GTX 560TI and most of my games run fine on mid-high settings.

We tried testing his card on Hitman Absolution's benchmark test (because that is what we had on hand) and got about 10-25 FPS on mid graphics settings. We then tried installing my graphics card in his machine and it jumped to 50-60 FPS.

At this point we assumed that the card was bad and he sent it back to get repaired. His new card has been behaving just as poorly. He tried installing another friend's EVGA GTX 760 SC and it functioned just as poorly as his own.

Has anyone had a similar problem and if so, what do you think its from? He is using a CORSAIR HX series HX650 650W ATX12V v2.2 PSU, which I thought would be enough for whatever he needed to run. The rest of the PC is just 2x4 GB RAM, 1TB HDD, Intel i7 Haswell, and an ASUS Z87-PRO motherboard.
 
Solution
Stress test programs:
Ram: Memtest86+ (do this one first)
CPU: Prime95 an Intel Burn Test (use both just not at the same time)
GPU: OCCT (only on GPU test with error check on)

Not sure what kind of stress testing to do (other than running a game, benchmark test program, or writing code to force the GPU to calculate something). As for the drivers, we already tried that a few times during out tests

Perhaps a faulty socket on the graphics card? Do you have another 760 on hand to check on his pc? Also what resolution are you using and what is the I7 number, like i7 3770k etc.

Thanks for the tip. We tested his machine and it turns out that his CPU was overheating every time he ran anything graphic intensive (Burn Test). It was peaking around 90 degrees Celsius a few seconds into the test. He installed an after-market CPU cooler and the machine now runs at 60FPS on ultra in the benchmark test we were using.
