Since you already have a 5770,then go with another 5770. 2 5770s perform better than 1 5850.
thanks for replying. how much better do you think they perform? im just wondering if two 5770's is even poewrful enough to play games like Metro 2033 and Crysis at that resolution. what do you think?
also how much hotter does crossfire usually run? and do you think i could overclock them close to 5870 strength. iv heard single 5850 can do that
