OK, so having an idea that we're got another year or so before thinking hard again about the next platform decision, it's back to the practicalities of putting a new GPU in. My workload: primarily computational photography in a Qt/OpenGL app that uses CPU for rendering (woo watching all cores peg on full is fun), but uses GPU for previewing / editing and UI. It's typical workload is stitching ~140 TIFF files of 200mb+ each. I've still got the original gt120 (which is really getting unresponsive while trying to edit), which I can plug into the TV that sits above my workstation, so if I absolutely need a bootscreen (I like watching verbose booting), that's covered. Do these cards coexist with newer AMD ones, or am I likely to have un-neighbourly issues? As an aside - when folks are referring to not having boot screens, you're effectively seeing a blank screen up until... the login prompt? Or, do you need automatic login enabled to get it to the desktop before the display is enabled? Which part of this process is where non-bootscreen cards kick in? So what GPU? The RX480 seems like a good choice, with a boatload of VRAM, single 6pin power (for the blower-style reference model), and significantly less expensive new than what would seem to be a popular choice - a secondhand 980ti (6pin 680s are rarer than roosterteeth here). I've looked through It Sage's RX480 guide and the threads here - having to run software update via commandline isn't too big a hassle (does that include security updates - or is it only OS versioning upgrades?). Any advice?
