Hey guys I'm new to the community and I don't know much about computers so I'm hoping you guys could help me a bit like last time.

SPECS:
Graphics Card: GeForce GTX 650
Processor: Intel i7 4770 3.4 GHZ
RAM: 32GB
Operating System: Microsoft Windows 8 (64bit)
Power Supply: Not exactly sure what I have in here, but I do know it's a 750W so I'm fine for now.
Motherboard: Ideacentre K450
Case: Not sure but pretty much I have a IdeaCentre K450 Desktop if that helps.
Monitor resolution is 1920x1080 and I plan to use only 1.

I was thinking about getting this on-sale:

But I'm not sure if it would be much better. Are there any other graphics cards that I could get that can maximize my FPS on most high-end video games? Preferably under 300$.
