Hi, I currently have a bit of a dilemma, I want to know if I will get better performance from a second 6870 rather than selling my one and adding money to it to be able to buy a single GPU. I would also like to know what would I have to do in order to get the best performance out of the 2 6870s and prevent micro stuttering.
My specs:
CPU: AMD phenom ii x4 965
Motherboard: asus M5A99X EVO
504w

I have re-posted this due to not being able to get a good answer first time round.

after updating my 6850 to crossfire 6850's I can tell you its not worth it. within a month of getting the second one I sold them both for a single gpu. too much stuttering in many games, you can use an fps limiter to remove some of that, but then your limiting your fps and not getting the most out of the card anyway. and the 1gb vram holds you back from using high detail textures in some games, really slows down and gets choppy when all your vram is used up. Just get a new single card, crossfire isn't worth the hassle.

I have crossfired 6870's, 2nd card was only £45. Performance is much better on all games bar Skyrim because I still only have 1gig graphics memory, crossfire memory is mirrored not doubled.

However keeping the same Skyrim settings (well upped them a little) is quieter than a single card a load is split between the 2 making fans spin less. Overclocking graphics memory also helps a very little bit.
