Point Taken.

I'm starting to realize that this is something that should be shouted from the mountaintops anytime somebody starts talking about linpack flops (i.e. most recent top500) as the determining factor in GPGPU decisions. I guess, as a fan of the underdog, I was hoping that AMD's higher theoretical peak would mean that they would catch up to Fermi, and in some instances they have, other instances they're still woefully behind.

Makes me want to have everybody standardize on one type of instruction flow, at least that would make comparisons easier!
