Sure they will work. They also support CUDA. ;)

how about using tesla's with cycles?
performance seems to be almost the same compared with high end gaming cards but will cycles work with these teslas?

> 1b.-if, in future, cycles uses multiple GPUs will it be still limited by the max amount of memory on one GPU or by the sum of all?
> 2.-Is the rendering speed mainly determined by GFLOPS?
> 2b.-if not, can you tell me what is?
> 3.-Does Cycles make use of any "newer" NVIDIA technology? I mean will an older GPU (cycles ready) with same specs as a theoretical new One render at about the same speed?
> 4.-Cycles doesn't care about Nvidia SLI, "just" (will) use all GPUs, right?
> 5.-Will cycles care about different GPUs (for example 1xOlder Cuda, 2xNew Cuda)
> 6.-Will/might it be possible to mix Cuda and OpenCL GPUs?
> 7.-Is there a chance that, in future, currently older GPUs like gtx 295 will drop out of Cycles support?
> 8-. just for private use: Do you recommend any GPU?

> 9.-I know you can't tell, but when you think will multiple GPUs be supported (CUDA)?
> 10.-Do you know/predict anything about significant speed differences (of cycles) between CUDA and OpenCL?
