I saw Xenoblade mentioned here and just thought I'd drop a line in case it's a concern.
As someone who has put hundreds of hours into Xenoblade, playing, dumping, and retexturing and loading tons of custom textures at a time (80,000+ atm), I would seriously recommend over 1GB of vRAM, but anything over 2GB would be overkill if emulation is your only concern.
I monitor my hardware constantly (I'm paranoid) including vRAM usage, and I see it go over 1GB quite often, but never even close to 2GB. You'd probably be safe with 1.5 even, if that's even a thing. I'd shoot for 2GB to avoid any issues, however.
