For those that are interested, this link compares h.264 codecs utilizing the ps3, the gtx285 and the i7 965 xe. The ps3 (not sure if they are only using the cell or if they are using the gpu in the ps3 also, but if I remember right, access to the gpu when running linux on the ps3 is limited, so it could just be the cell) and the gtx285 were close and the i7 behind both of them.
