Back to impractically high EUE rates on my GPU, to the point where running a single cpu client can out-PPD my GPU. I'm beginning to suspect hardware instability because my IGP was stable (although not fast enough to justify using it).
I won't buy another GPU because it seems the GPGPU "gods" hate me for the time being. My Radeon 4850 has its good and bad days, while my nVidias (8400M GS, 8500 GT) EUE'd on the first WU attempt I tried with them (not to mention they're too slow to be practical).
I'll OC my CPU more in an attempt to compensate, since SMP client has never failed on me yet
