So..., I set beta on my GTX 460's and got 9401's. Only problem is that they are on a A8N-SLI motherboard and it appears that the "slow" PCI-e or 3200+ processor is bottlenecking them. TPF is up to 4 minutes slower than my slower GTX 460 in a PII 805/880g system. Lesson learned: Don't build a F@H box on REALLY old hardware. (I'm working on getting a P55/i5-750 to replace this) My GTX 560 Ti is doing TPF 18' 53" with an estimated credit of 36781 and PPD of 28048 on the 9401. These might put an even greater load on the CPU than previous core_17 WU's.
