Yes working now - just managed to clear my backlog
I've been offerred a good price on nVidia Tesla C1060 - dont know how good that would be re. Seti CUDA ?
Looking at the specs of the C1060 it looks like a GTX280 with additional albeit slower memory and no external outputs.
GTX280
Shaders 240 @ 1296Mhz
Core 602
Mem 1024 @ 2100Mhz @ 512bus
Tesla C1060
Shaders 240 @ 1296Mhz
Core 602 ?
Mem 4096 @ 1600Mhz @ 512bus
I cannot comment on any software optimisation the Tesla drivers bring but unless you have a use for the additional memory I would imagine no real difference between the two when running Seti and of course the added advantage with the GTX280 ...you can play COH

Cheers, Simon.
