Highly Recommended by Pro Clockers *SAPPHIRE HD4850 X2 2GB GDDR3 PCIE *
The performance in which the Sapphire HD 4850 X2 is just what the doctor ordered. It is ideal for the gamers and enthusiants that want near-top performance for minimum cost and that is what the 4850 X2 is.
We can mention all the wonderful features which this card may have that makes its performance so great but what is really wonderful about the HD 4850 X2 is its overclocking. We believe any extra performance numbers you get from a video card is great but when you are doing it on two cores and two sets of ram it is wonderful.
We managed 690MHz on each of the cores and atleast 1183MHz on each group of ram sets for more promising numbers.
