yep i've seen an article here
http://tweakers.net/nieuws/43490/Kentsf ... -4GHz.html
claiming that we should expect an 2239 Cinebench score
for info
a Dual Opteron 285 mobo scores 1616
my current sytem is a dual dualcore opteron 270 that scores around 940 cinebench that as represented a boost of 5.6 in most case compare to my old P4 2.4 that was around 245, that to say it doesnt scale comparatly, so i do expect a big slam for next years renders ( maybe a render that took 30 hours with maxwell currently would only take 8-10 hours )
