So i'm finally going to update my ancient rig with a new mobo, ram and processor.

Pretty much an i5, gigabyte and asrock mobo, and either kingston or g.skill ram. Eventually, the innards of my old rig will be fully replaced with up-to-date equipment, but I need start at the heart.

Catch 22: I'm chiefly a Debian Linux user, but also decided to get a better processor to handle things like photoshop and OpenGl stuff in Windows. Problem is UEFI.

What experience do you folks have with Linux friendly mobos?

UEFI shouldn't be much of a problem sans certain specific options in the BIOS you may have to keep disabled. Most if not all motherboards also have Legacy mode where it falls back to old BIOS rather than using UEFI. So if all other options fail, legacy mode should work just fine. You can check beforehand from motherboard manual whether it has an option to use UEFI or Legacy mode, manuals can be downloaded from manufacturer website. Most of the time UEFI support is only included with 64-bit editions of distros.

It seems Ubuntu has pretty decent article on state of UEFI. https://help.ubuntu.com/community/UEFI
While Debian usually trails way back behind Ubuntu because of its stupidly slow release cycle, I'd still imagine things to be about same in Debian since last stable release wasn't too long ago.

Well, if Ubuntu wasn't full of stupid bugs and the usual slew of problems, I would like to use it more. I fell back to Distros that run Debian Testing because I get more "advanced" stuff known its built from the Testing repos as opposed to the Unstable or experimental builds.
