Hey everybody, as a 3d and 2d artist, I'm starting to see the power of my 560 gtx graphics card diminishing. I was curious, if anyone knows, would a better gpu benefit Krita? Currently I'm painting pretty good at 4k, but I'd like to go 16 bit too. Your thoughts?

To get good answers that might actually help you, you'll need to supply some more information than you have.

The most obvious questions:
* Probably most important, what OS are you using? Driver quality varies by brand and OS.
* What's your processor brand, type, speed?
* How much RAM?

Depending on the answers to these, you may need something else more than you need a new GPU.

Sorry, I just figured the graphics card is doing the brunt of the pixel work. My Specs are,

Windows 8.1
Quad Intel Ivy Bridge 4.6 GHz
2x nVidia GTX 560's
8 gb DDR3 RAM

My CPU certainly couldn't be an issue for more speed, note i just lag mostly with bigger brushes, more on 16 bit. Wraparound mode can also be very slow with some brushes at 2048 x 2048.

Okay, definitely not a weak system there. Doubt you need to replace the GPUs, either, honestly...

Might be a Windows port thing (couldn't say, I don't use that one), or maybe just some of the brushes are really slow. I've noticed the brushes vary greatly in performance, but my system's kind of old, so I can't tell what's slow because of my system and what's not. In my experience, most of the brushes work fine, even on a large canvas with many visible layers, up to around brush size 150 to 200, then they start to get visibly slower. Maybe someone more familiar with the brush engines will provide some insight; I haven't done much more than tweak existing ones a bit here and there.

The things that kill performance for me are editing layers with layers that have visible layer effects (extremely slow), and, strangely, having the ruler turned on. (The ruler thing probably isn't relevant for you. Seems to only happen with certain types of tablet for me, and at any brush size. Some sort of bug.)

Oh, and turning OpenGL off in the settings makes Krita run horribly, obviously, but you probably already figured that out without being told ;)
