I have a radeon HD 4850 from about 2 years ago and I'm looking to upgrade it without spending $200+. From what I've seen, two of these cards perform pretty well so I really just have a question about the crossfire compatibility. I found another 4850 (which was a task in of itself), but looking at the specs the card is slightly different.
Everything looks pretty much the same except for the fact that the one I'm looking to purchase has a HDMI slot whereas the one I'm currently using has a s-video output in its place.
Basically, just wondering if this will be enough to make the two cards incompatible for crossfire!
4850 CF and 6870 is quite on par in terms of performance (with 4850 slightly ahead) but 4850 CF have to deal with scaling while 6870 is not. i think the chart positioning is based on 4850 near perfect scaling. personally i would chose 6870 because of 6870 is DX11 capable card but the choice is yours
