Feasible to install on this hardware?

I have read the configuration guide (which I find fairly useless as it doesn't list the actual minimums) and lots of posts on the forum and I know that I am probably on the edge of minimum specs for actually using DaVinci Resolve but I want to try it out before I embrace it fully and upgrade my machine. So is it feasible to edit, basic colour correct and use to some extent the new integrated fusion toolset on the following machine?

Dual Xeon E5472 (3.0GHz old processors)
32Gb Ram
Geforce GTX 680 with 4Gb

Now I know the 680 is lower than the minimum for CUDA specified but Peter mentions being able to switch to OpenCL as an option -- is this possible and is anyone doing that?

Which OS should I try this on?
I am CentOS literate and have no qualms about going down this route but my current OS is Windows 8.1 if I try and install the 15 beta it complains about DLLs. Should I keep trying with Windows 8.1, install Windows 10 or go for CentOS 7.4?

Thanks

That's a bit of an ask, but is doable in theory.

Win 8.1 can be used for the 15 beta. Here's some instructions on the DLL.

As for the GTX 680, you'll see a rolling log here - the 15 beta does recognize the board, but disables RED GPU decoding due to insufficient CUDA support.

If you're happy with Win8.1, you can go with that and try the 15beta out. You are likely to stumble on some limitations (lack of H264 encoding, IIRC), but the software can be ran. For full functionality, you'd need to upgrade to W10 - or to downgrade your W8.1 Resolve to 12.5.6.

The Linux port is slightly different in its ways, and CentOS is hardly the optimal platform, all things considered.

FWIW, can't speak for the GPU, but am very happy with Win10 & DR studio.
