If you've got a crossfire board just get another 4850

If you can afford a 1GHz card, I'd go that route. If you can find a XFX card (double lifetime warranty, amazing support), go that route. If you can find the new XFX 1GHz card due out any time, you have a winner.

I got my XOC 4890 w/ default setting 925core/1050 mem.... I run it at 950core/1050/mem with no issues. I have check it on crysis at 1000core/1050mem with no issues. I would say that my results are specific to my setup. I may have been lucky with my card.

You can tweak the two clocks to find a stable setting for your card.


The core clock is the speed of the GPU. The memory clock is the speed of the frame buffer(1G DDR5).

Higher GPU speed has a better impact than higher memory speed. Below is a reference done by ANANDTECH on overclocking 4890. It differentiates the impact of overclocking GPU and Memory.

I got mine on sale for $229.... No premium charge for the XOC version for that day..

Almost all i7 boards are crossfire capable. To make certain open the case and look at the port the video card is plugged into. If there is another one that looks the same then you can crossfire.
For crossfire you just need any another HD4850.
