Not anymore. GTX295s are the current top dog of GPUs. The box I'm getting for this project will outrun that system significantly.

Ok, so when you say significantly, how much are we talking? Any est of how many tflops, cuz it seems that with a few of those one would be getting close to the old bluegene #'s. And all I can say to that is DAMN, I feel old =).

if he told you 4TFlops what would that tell you ? the number of FLOPS is only a theoretical number. much more intresting is the fact what the gpus can do with given software such as bars or the multiforcer (which does not support multigpu YET) :P

Oh, somewhere around 5 to 5.5 TFLOP theoretical.

Estimated performance with the current Multiforcer would be around 2.5B MD5 per second on a single hash, and around 180B checks per second with 1000 hashes.

FLOPS are meaningful... just not for cryptography :P
This is all integer math and bitfields, so it doesn't matter for us if the GPU can do floating point math at all.

There are several things which can be supported for the best to use is FLOPS these is really one of the meaningful . In all these it can be supported system significantly these all are great to know about it.
