Help with Graphics card ?
Im looking to buy a new GPU and im set on a 5850, but they are out of stock in every store i find, so i came up with a solution. 2x HD 4890's crossfire, would that be better than a single 5850 ?
Two HD4890 in crossfire will handle anything that is out to date and in the foreseeable future. In the US that combo costs less than 400 USD a HD5870 is over 400USD for less performance but DX11. At the end of the day it is your money!
Yeah, crossfired HD4890s will be quite powerful. Personally though if I was laying out that kind of money for video cards right now I would definitely want them to be DX11 compatible. Also HD4890s use a lot of power and put out a lot of heat so you need to make sure your PSU can handle them and your case has good airflow.
An alternate suggestion is crossfiring HD5770s. They should give you performance close to an HD5870 while being DX11 compatible as well. They are also 40nm so the power/heat issues that would come with 2 HD4890s would be largely alleviated.
