Dear
Sure No ; Upgrade to a GTX 970 not a 760!! New Maxwell architecture that is more power efficient and run more cool ; fully directx 12 compatible (more future proof) // it matches the performance of 780ti and even super-pass the performance of 780 OC from Asus. - 4GB of VRam from is a cushion for future games that require more RAM (A real life example now is Watch Dogs)
http://www.xbitlabs.com/articles/graphics/display/msi-geforce-gtx-970-gaming.html - the 970 is cheaper much cheaper than a 780Ti and also cheaper than the 780
I get the MSI GTX 970 for my New High End Gaming Rig Assembly :) -Read the above review for more details of what I have referenced
Also what CPU are you using ; Since the CPU might bottle neck a high end GPU
In a Knot-Shell:
The GTX 970 is far more better from the 780/760 or even 780Ti from all aspects. It's insane overclock-ability and low TDP are the most favorites among all enthusiasts / gamers therefore skip the 760 and get this awesome GPU
