Yes there would be a bottleneck. You may just want to hold off and save for a whole new system.

Would I notice a big improvement on FPS in gaming from what I have now to a 660 card?

 

[Norlag]

There's no point in getting a medium end card if your cpu will just bring it down to low end level, which you already have.

 

[PMcConnell]

So the GTX 650 I have now is probably the best I'll get on this machine?
What would you recommend to run a 660 at it's best?

 

[Norlag]

Most medium end modern cpu's will work very well with a 660.

For amd I would go with either a 6300 or a 8350.

For intel either an i3 3220 or a 3570k.

Of course that depends on what you want to spend. You would have to replace the mobo for any of these.

Ok, thank you. Looks like I'll wait on the GPU upgrade and start saving up for an entirely new PC.
