lyclminer will do lyra2rev3 on pretty much any old GCN and pre-GCN AMD card, lyra2rev2 was break even during the big boom a while back on my 6870 even, you'll lose a bit now unless you have free power. as for nvidia.. well, I don't think you're going to have much luck with anything prior to Maxwell, nvidia stuff wasn't great for mining in general before it. Maxwell (the 750 Ti specifically and the whole 900 series) isn't that obsolete, a lot of stuff will run on it fine. With 2GB of VRAM a few ethash coins should fit and run "efficient enough" but not very fast, a little better on linux. Some of the x16r miners probably support it, not sure if it's too late to get in on progpow for BCI but I've tested the ethminer fork on maxwell cards before, I would expect phoenixminer's support of it to work too. expanse and ubiq are 2 ethash coins I've run on AMD 2GB cards recently. I think ubiq might have some customizations to the algo, but phoenixminer supports it, haven't looked too far into that detail.
edit: for old GCN hardware, my HD 7850 was able to get 17.9MH/s on SMOS mining ubiq. Callisto is what I used to mine on it, but it seemed the 1.75GB DAG wasn't fitting into the vram anymore, even on linux. the same card maxed at 10 at stock on windows, 14 With a high OC. 17.9 on ubiq with 120-140W is below break-even for me. R9 290s get about 30 on linux, but they have 4GB of vram they can mine etc and eth at 28-29MH/s and that has higher revenue. My kill-a-watt died so I can't measure them now, but I'm assuming at -very- high power. I don't have other old hardware like HD 7950 or 280Xs to test.
