Mine are not reference, they are the evga FTW Hydro Copper 1 and 2. But his also was overclocked. I'm surprised though that the 660 runs at that rate - I'm glad it's quiet.

[QUOTE=Xyzzy;371789]When we ran our 660Ti it was good for ~275 a day.[/QUOTE]Remember the 660 Ti has 30% more GFLOPS than the non-Ti version that [i]Gordon[/i] has.

Video card nomenclature is too confusing!

Please do try to keep up.

Recent Ti-suffixed GPUs have roughly a 25-30% boost over their non-Ti counterparts:[quote]GeForce GTX 780/Ti +27%
GeForce GTX 750 Ti +25%
GeForce GTX 660 Ti +31%
GeForce GTX 560 Ti +16% (+20% for the 448-core version)[/quote]Where it gets more subtly confusing is when the same model number is used for dramatically different-performing GPUs. For example the GeForce GTX 460 (907 GFLOPS) should not be confused with the GeForce GTX 460 (1046 GFLOPS), nor with the GeForce GTX 460 SE (749) or the GeForce GTX 460M (518).

Iffy GPU
 

I'm bringing up two second hand cards I just got my hands on, two Radeon 6950. One is running just fine but the other one have some random hardware errors and are failing circa 1% of the tests in the -st2 self test.
Is it okay to use it for TF? It still finds 99% of the factors.

I like to push the edge of humor. Mike understands....

Is it overclocked?

[QUOTE=kracker;371755]Hmm, so you're getting less out of dual 660's than a 580 with less sound and more power consumption.

EDIT: Is Kepler really more power efficient W/GHz? Hmm...[/QUOTE]

It's the sound that's the killer for me, the 580 was like sitting next to an industrial blower unit :lol:

[QUOTE=Aramis Wyler;371785]That doesn't sound right to me. Are you running two instances of mfactx? Or maybe you mean 375/card?

On my gtx480 + gtx580 I get 820 GHD/day in the 69M range with 2 instances of mfactc..[/QUOTE]

Pailt GTX-660 - stock speed - 171 days/day
