I just bought a board which supports CrossfireX with four PCI-E slots; and I'm planning to get dual HD4850's for it.

But I was wondering, does ANYONE out there use Quad-Anything (Or CrossfireX) with four physical cards? If so, how is it? I heard the drivers are crap and there isn't a lot of gain, or they simply just crash in 3D applications.

Anybody can shed some light on this situation for me? How about three physical graphic cards?
 
Quick answer, not really. There are some gains for 3x or 4x Nvidia cards, mostly with CUDA, not games. A 3rd 280 scaling isn't great, but it is there and if you don't care about money it's probably worth it. ATI, not so much though. Even 2x 4870x2s are really bad at scaling verses a single 4870x2 and you can't do anything on CUDA with them.

Anything on the above talking about games assumes your running at 2560x1600. If your not, don't even bother.
 
if you want practical, buy a treasury bond. if you want stupid awesome, go quad.
 
I dont honestly think it is practical because by the time that programs are fully optimized to utilize quad-cross or quad-sli there will be better alternatives as far as cards are concerned.

But thats just my opinion
 
it's practical if all your bills are paid, and you have the money to spend. Otherwise, no. Not practical at all knowing one can typically get by with a single card and according to your sig you're looking for a cheap $50 sata drive...
 
You're going to need a 1000W PSU, if not more, and enough wattage on the rails.
