Can anyone tell me if I am going to get errors if I use two different GPUs in one PC?

I do not know if I need to worry about tasks starting one one GPU, getting paused so another project can run, then starting on the other (different) GPU.

I used to run GPUGrid on a GTX 660 and a GTX 650 Ti on the same motherboard with no particular problems. It is possible that if you reboot, then a work unit might jump from one card to another, but that was not a problem for me even if it did. If you simply want to pause a card, then enable "Leave applications in memory while suspended" and I don't think you will have a problem.

Thanks for the comments. I think the problems were caused by one of the cards - it totally failed a few days later & since then a GTX660 & a (previously retired) GTX570 have been playing together just fine. :-)
