6850:
- Single card means no CF Issues.
(not a big issue nowadays, but still an issue with newer games that AMD hasn't had the time to adjust the drivers for / any game you play in windowed mode)
- Can add a second 6850 later for cheapness.
(Although by this logic, you still ought to go with the 4850)
- Lower power draw
- Lower number of PCIe power cables required.
- Less space taken up inside the PC.
(Which will mean that it shouldn't get as hot)
- Directx11 support
- New technology comes with new warranties

I can't think of many more, but my point is that the cheaper and the faster tend to be what most people want. If the others (especially Dx11) bother you, then consider the 6850. If not, the 2x4850 will be about as fast as a 6870 (maybe a touch faster, but we'd probably be talking in the region of 1-3%).


Why do you want a new card? Depending on the prices I could find a 4850, I'd probably crossfire it. That is, if my PSU could handle it. Yours should handle it easily, I think.
6850 hands down, I'm getting rid of my crossfire setup due to all the issues. 4xxx cf was not completely mature, however the 6xxx cf seems to be problem free for the most part.
I know crossfire is very enticing especially since the cost is so low compared to making the jump but I really believe you would be better off with the 6850.. plus it's definitely faster when overclocked. 4850cf = gtx 460 768mb stock (to make things easier for you when looking at new reviews).

I'm sorry, but having compared them side-to-side, the 4850 cf gets (slighly) more fps in Crysis, and a slightly higher Heaven and PCMark06 benchmarks than the 6850. 4850 cf is more like a very heavily overclocked 460 1GB/HD 6850. I've got my 6850 pushed to 975/1125 (from 775/1000 stock) and I can tell you that even overclocked to that point, I still come behind the 4850's on Unigine Heaven Benchmark @ 1080p in Dx9 or 10. It's not by much, but it is behind. If you want, I can probably get you screenshots - one of an Athlon II x4 running with DDR2 RAM and 4850cf and the other of my rig (A Phenom II x4 running DDR3 RAM and a single 6850). I can even do before/after overclocked screenshots for you.

The 4850 is faster. Even if only by 3-5%.
