Here are benches of the 560 Ti vs the 4870. Note that they don't have benches of the plain 560 (non-Ti):

This site is better. Ive picked non-Ti. 60-100% average.

4870 cannot downclock properly as well (all pre R700).

I wonder if we ever will get GPU to work as pluggable CPU cores - plug more and get equivalent boost. On best - without drivers. Would require smp-friendly software or hardware tricks.
