The GT610 runs Portal II without any issues. Shooter? Quake4: no problems. I doubt kicad has higher requirements for 3D rendering than any fairly recent 3D game.
If Micro$oft artificially cripples “old” cards on winblows 10, I don’t know.
Just don’t waste your money 
but you haven’t tried in windows 10 do you?
so I’m asking advises for windows 10 (64b)…
thanks
maui,
Just make sure the drivers are available (OpenGL above v2.1) for Windows.
I didn’t have luck with that after upgrading to Windows 10. Chipset maker and Microsoft doesn’t want to make newer drivers for my 2009 machine. Ended up running Linux now.
I forgot to give a feedback… it took me quite a while to upgrade my pcs…
I’m running kicad 4 or dev release on a win10 64b machine with a geforce gtx950 card and it is blazing fast!!!
OpenGL or Legacy canvas…
Thanx all for advices 
Maurice
ask how do I install the drivers and put OpenGL 2.1 in Ubuntu 14.04 ???
Ubuntu 14.04 went out of support a VERY long time ago
