I am still lacking data points on compute 1.0 and 1.1 devices (8800GTX, etc...), and also compute 1.2. Really ancient hardware
I actually have a old box with an 8800GTX in it! I will run it for awhile and report my results.
Update:
Autotune picked 1x4
Hashrate of 2.4 kH/sec
didn't bother which much more testing due to such a low rate
