Dual GTX 550 Ti or Single GTX 560 or Ti

So I was thinking about upgrading my pc because I will be getting a new and bigger monitor. Currently i have a gtx 550 ti and was thinking about getting another, however, im not sure if my mobo will use both cards at full speed. I have this mobo: http://www.gigabyte.com/products/product-page.aspx?pid=3897#ov. Another concern I have is about the power supply, currently I have a 450 watt xfx, will I need to buy a new psu to support two gpu or the gtx 560/ti? Oh and I have a i3-2120 cpu, do you think it will bottleneck?

  1. Just get a 660 gtx, the xfx 450w will do for a 660 gtx, but not with two 550ti or 560 ti + 550ti for physX.

    A single 660 gtx is better than two 550ti or a 560 ti+ 550ti physX.

    Ah that is a much better card, I will be going for that instead of 550/560 ti but then I Found this: http://www.tomshardware.com/reviews/gaming-graphics-card-review,3107-4.html , it is a Radeon 7850 2gb which cost less than the gtx 660 but im not sure which one is better.

    The 660 gtx is better than the 7850, the 7850 is cheaper.
    If you have 200$ to spend get the 660 gtx, it's better.
