Okay - since I'm already just about tired of dealing with the GPU issues, I'm thinking it's time for (really, TopHat - really?) another upgrade. I'm currently using a GTX 550 Ti in my main build. Should I go for a better workstation card from a later gen?

It would be a pretty cheap upgrade, since no one wants these GPUs now, and doesn't come with the price gouge of going straight Pascal or Maxwell. Either that, or I could go Kepler instead (and hope the prices aren't too scary since they're pretty close to current gen). There are also other Quadro options I have been eyeing:

What do you think? Most of these can be had for under 150 USD, so I can afford these within a few days. But, should I go for a Geforce card instead? If so, what card (above the GTX 750 Ti, preferably) should I go for?
