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.

Remember the 660 Ti has 30% more GFLOPS than the non-Ti version that Gordon has.

Video card nomenclature is too confusing!

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)
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).

Default 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.

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

On my gtx480 + gtx580 I get 820 GHD/day in the 69M range with 2 instances of mfactc..
Pailt GTX-660 - stock speed - 171 days/day

Gigabyte Windforce x2 - 200 Mhz overclock - 207 days/day
