i play at 1080p so i think gtx660 is fine. gtx660ti might be worth it, but its not avaliable in NSW at a cheap price...
Are you planning on the 660 or 660TI?
Definitely think you should get either the 760 or 660TI. The 760 has higher bandwidth so if you're running high resolutions I would recommend getting it. Otherwise just get whichever is cheaper between the two. Both have similar performance.
Good luck on your upgrade

7950 could do or 760
760 better at stock
7950 better at OC
about the same price
i have a 500w power supply, is that enough for a 660 or 760?
I think yes, but you should get a 600 wat one to be sure
Get a GeForce 670 instead of a 660, or 760
END THE FED
Just upgrade your GPU, all the other parts are fine
