I have 4 120MM fans blowing on the case side and I encountered numerous lockups at stock speeds. Default fan speeds suck and hopefully rivatuner will allow for adjustments. Crossfire doesn't scale all that well on my current motherboard. I had various lockups and performance wasn't that impressive. Other reviews seemed much better. I loaded updated 8.6 drivers and the Vista X64 hotfix, but nothing really mattered. Ati should drop the price on this thing closer to $130 for this to be a decent deal and use a better cooler. I'm sure others might have better luck with a dual x16 Pci Express board, but I still expected more out of this with my P35 chipset. I think I'm going to stepup to a GTX 260 and trade-in my G92 GTS. However, I would definitely recommend the G92 GTS over the Ati 4850 at current price levels and I would be cautious with crossfire on certain mainboards because YMMV.

Final conclusions: (1) seems slower than a G92 GTS for around the same price and (2) G92 GTS runs cooler and overclocks like a champ



You should have spent 5 minutes googling about your board+Crossfire before spending ~400$ on graphics cards..
Don't.. ever.. do.. Crossfire.. on.. P35s..


Anyway, just take off your second 4850 (the one in the 4x slot) and you'll see that a single 4850 beats your "old" G92 GTS.

And don't worry about the temps, these new GPUs are ready for that (8800GTs used to do 105º with the old cooler). The lockups aren't temperature-related, that's for sure.
