So, I was looking at video cards, and I found that I can get two hd4850s on Newegg.com for less than $100!!!!!! Super exited, I started searching for a video card that compared against them that performed well. Well, I think I have come to a conclusion, they match a hd5850 stock clocks. So, I am on a budget build and thought that these two video cards would be great. Now, this is not a hd4850 x2 card, it is two hd4850s in CF. Would this match a hd5850 performance wise, how far could I OC those video cards, what temp do they reach, and will they last me a while performance wise?
