I currently have a gtx 460 768 mb card and would like to upgrade to either a gtx 660 ti or a hd 7950. I only have around $300 and would like to keep using my 520w psu. I've been hearing that the HD 7950 is more powerful especially after the new drivers and at the same price as the gtx, but the gtx 660 ti only needs a 450w psu. Can I use the 7950 for my current psu or should I just not bother and get a gtx 660 ti?
