Recently I had to upgrade my power supply because the fan in my old one somehow decided to start rubbing against the side of the power supply and soon shatter, so I had to go ahead and buy a new, better, power supply.

That is my power supply

http://www.newegg.com/Product/Product.aspx?Item=N82E168...
That is my motherboard


http://www.newegg.com/Product/Product.aspx?Item=N82E168...
That is my *CURRENT* video card.



Anyways, the deal is that I'm a solid MW2, Dirt 2, and Bad Company 2 player.. 2 out of 3 of my favorite games have DX11 support, so I am going to upgrade to one of the new ATI cards, my only hold back is I am not sure whether it is better for price/performance to get two 5770's, or a 5850.
I have two monitors, 25" and 22", they run at 1920x1080 and 1680x1050. I only play on one monitor (obvious) and use my secondary for multitasking. I'm powering this with an AMD 940 Phenom II


Does anyone have any suggestions?

If I get a 5850, this will probably be it.

Or I could get maybe two of these?


I'm not too savvy when it comes to video cards, does anyone have any suggestions? I'm not sure what is better for performance: two 5770's or a 5850

Please help me out here

also I'm not sure if my MOBO can support crossfire 5770's

2x 5770 rivals 5870 in performance. A HD5850 would though leave your second slot open when the need arises fore an upgrade down the line.

2xHD5770 in Crossfire will perform better than a single HD5850.

I can not find reviews that contains your favorite games but I think this benchmark will be about the same.

Your mobo will run 8x8 crossfire (not a problem with 5770). Your power supply is bigger than the requirement for 2 xHD5770 in crossfire.

No it is not worth the cost. The only cards that get slightly bottle-necked by the 8x speed are the most powerful ones like HD5970.
