Is cudaminer dependent on processor performance to give better hash rates?

with -H 0 and -H 1 options the CPU can become a bottleneck. Otherwise no.

actually for scrypt and scrypt:2048 you get an extra 20khash/s (scrypt:2048) with H1 compared to H2

interesting. -H1 does 4 times more transfers over the PCI express bus than -H 2. Surprising that it's faster. I intend to get rid of all the transfers and do the hash evaluation on the GPU soon (like I do when hashing Keccak). This will allow us to run nVidia cards with 1x connections through risers without performance impact.

Maybe for users with only one card in a system? Multi-cards = bad?
