So recently we've noticed a lot more issues with the Graphics cards we were using.
Originally we were told (by our re-seller) that you don't really need a workstation level graphics card for Revit since it not that GPU intensive. They suggested using a basic gaming card. Currently I've to a GTX 760. It runs ok but I hit some snags where revit will close a window cause the "view is corrupt". Or you can't pick on anything until you minimize then expand the window again. I've also had some other workstations where I had to turn off the Hardware Acceleration to get the model to not crash.
I see that Adesk hasn't updated the certified cards for suites for some time.
About 2 years ago when we spec'd out our workstation requirements and picked out a card and a driver, I ended up with a GTX 650 and an older version of it's driver. Took me forever to figure it out. But once I did, that set up still runs flawlessly. Only problem is by the time we figured out the entire set up, you couldn't buy that card anymore.
So in this era of Graphics cards going obsolete within 3-6 mths, how do you pick a card for a workstation that's supposed to last you for 3 yrs?
Also with all the monitors seeming to be going to 4k, how do you pick one?

We need to purchase next years allotment (about 75) of workstations in the first quarter next year. Where do I start with the graphics cards? I don't want to spend $1000 on a card when I've seen very little performance gain with a high end card when we tested it. I also don't want to turn off the hardware acceleration and decrease work out put. I also don't want revit to crash cause you picked on an item in a 3d view. Or any of these other goofy things.

Any thoughts would be well appreciated.
Thanks in advance.
