Where are the hybrid crossfire capable GPUs?

is hybrid crossfire dead? then why there are still new mobos with new chipsets include this feature? im a cybercafe owner and budget is my primary concern in building a rig. using IGP (radeon 4200) is good enough to play casual games. but i wanna enhance it by enabling Hybrid crossfire. the problem is: Radeon 3470/3450 hybrid capable cards are so rare. i think its already paced out. and if you can find a rare old one, this is even more expensive than radeon 4XXX-series discrete GPU because its so hard to find nowadays.
