Melderv :
Yes, you can play BF4 on Medium and close to High settings on that resolution. I don't know your CPU, but if it's capable enough you can probably do a lot more with it. You'll have no problem maxing out current games if there's little to no bottlenecks involved.
I would not say "max out current games" but any game should be fairly playable if he TWEAKS the quality settings when needed to achieve a sufficient frame rate.
You'll especially need to carefully tweak demanding settings like AA (anti-aliasing), or DOF (Depth of Field), AF (Anisotropic Filtering) etc.
Run FRAPS while tweaking to monitor the frame rate.
My advice for tweaking BF4 depends on whether screen tearing is an issue (VSYNC OFF) and that can vary by the PC and by the game.
VSYNC OFF: aim for 40FPS average
VSYNC ON:
Turn VSYNC OFF to tweak until you achieve over 30FPS at least 90% of the time. Then turn VSYNC ON again. Despite what FRAPS says with VSYNC ON you should really be synched to 30FPS as long as your PC can generate at least 30FPS.
VSYNC Pros and Cons:
Pro - no screen tearing.
Con- can feel sluggish at 30FPS (buffer delay to synch with monitor)
I could give you a very long list of games the HD7750 can't come close to "maxing out" but again learn the basics of tweaking the games for the optimal Quality vs Framerate.
