Unless there is something new done with the ATI implementation, the nvidia would still be a better performer for F@H. Last time I read something about F@H GPU, the nvidia implementation uses CUDA, whilst the ATI uses Brook (which isn't capable of using an ATI card to its fullest).
If the ATI implementation has been updated to use Stream/CAL, then it might actually start competing with the nvidia based one.
yes , the ati client is still based on r600 (hd 3000) and they still havent updated it . perhaps the next major update would be not cuda or brook , but openCL to eliminate unnecessary development of different clients , just a consolidated one .
the folding team develops clients , but has to works with both ati or nvidia . this "bottleneck" would be reduced .
it would be interesting to see the folding performance on fermi with the supposed 900 gflops double precision and 1800 single precision , and radeon 5870 with 544 gflops double/2720 gflops single precision (yeah , ati has more single precision but lesser double precision performance , it really dont know much either are used in folding ) with a core to take full advantage .
