Well the i5 750 is definitely starting to show it's age in some of these newer titles, such as BF4, which chews up any and all processing threads you can throw at it. Newer games, such as BF4, won't be maxed out at a constant 60FPS by anything less than a 780 on the nVidia side, or an R9 290 on the AMD side. It really depends on budget, as it may be more effective to upgrade your mobo and CPU, and then wait a little to grab a new GPU.
