If it is anything like the CUDA version, it's because with 32-bit vs. 64-bit memory addresses there's half the data to keep track of.

Could try rebuilding mfaktc without MORE_CLASSES defined. And maybe change to Stages=0. I'm wondering if there's some overhead in such a short time/class that's hurting performance a bit?

Control-S in the mfaktc window works under Windows, so you'd think it would work under Linux too. Control-Q (or any other key in Win) to continue.

Same with the power supply. There's a decent 600W corsair for $60 after rebate on newegg, and even the 500W for $40 AR would be fine. Unless you're looking to run multiple GPUs eventually, 500-550W...
