I ran a single 5870 fro a couple weeks and in most games, it bettered my GTX 285s in SLi by about 15%, both minimum and average FPS.
Can you elaborate on the increases one 5870 gave you versus two 285s as that seems kind of odd.
I'm on the fence on whether or not I should sell my pair of 285s for ATIs latest, so any detailed info would be great.
Thanks

I am using (2) XFX 5870's in CF with water cooling. I was able to overclock them to 960/1300. I am only using one (large) monitor for now. I have no flickering or any issues with them (one of them was bad after 1-2 weeks of use and had to RMA it and the new one is fine) and the performance is stellar. In one thread someone posted their 5970 Resident Evil 5 benchmark numbers and they had ~122 FPS and with the 5870's in CF I get ~166 FPS running the same settings. I have not had any in game issues except for on Steam in Left for Dead 2 where at the start of each map you have to Alt-Tab out and then go back in so that the FPS go back to normal. This is a known issue and hopefully will be fixed by either Valve or ATI drivers. I am using the 9.11 official drivers. With the small exception of Crysis all benchmarks/games are out of this world...just go into the settings put everything to max and enjoy.
I look forward to going with Eyefinity when it supports CF mode. You will LOVE 5870's in CF. hope this helps
I'm also using 5870 CF with water cooling (the PowerColors with EK blocks). Surprisingly with the low temps (40c idle/52c load), I'm only able to OC them to 920/1330. This has been, well, very disappointing since I could have just bought a single 5970 on launch day and saved $200.. I'll probably be flashing to up the voltage at some point.
My experience has been just ok -- not surprising since I replaced two 4870 X2s. Performance in games is about the same or sometimes a bit smoother. My cards sporatically produce the blue/green dot issue in 2D, but this has ameliorated a bit over the past couple days (not sure why...).
The main reason I got 5870 CF was to handle Eyefinity. Unfortunately, Eyefinity only works with one card at this point, so for the time being, my investment is not paying off.
