They need to lower the HT from 2.8ghz to get more OC.
This A2x4 can do quad fire with 4x4890's even with the ""old" SB600 boards (K9A2/M3a32) regardless of which core it's based on (Deneb/Propus).
Can I do quadfire (besides 2 x 4870 x2's/2xGTX295's) with P55?
Didn't think so

More (3d) performance for 1/2 price -I think we have a winner.
