I'd trade half my GPU performance for the NVIDIA drivers not freezing my system on wake-up. The new half-open ones arguably made it worse, it consistently freezes now.
Now, it's been barely a couple of months since I reinstalled Ubuntu, and a couple of weeks since I found out the latest release runs even worse, so this is new to me. I don't plan to use Windows at home ever again, so I could sell my GPU and buy AMD, but so far I'm simply disappointed.
