Photoshop Crashes after GPU Upgrade

Question

I just recently upgraded my GPU from an nVidia GTX 460 to an AMD Radeon R9 290, and since then I've been experiencing problems with Photoshop.
Just after I upgraded my GPU, I did a clean uninstall of my old drivers, installed my new drivers (which I also updated to the latest version [13.12] just today), and tried using Photoshop.
At first, I was prompted with an error dialog saying that Photoshop could not detect my graphics card, so it has disabled OpenGL support.
I ignored the error, and proceeded to editing an image, but after a few actions Photoshop crashed, prompting me with the 'Photoshop has stopped working' windows dialog.
After restarting Photoshop, I went to Edit -> Preferences -> Performance and checked the GPU Settings box, which was now grayed out.
When hovering over it, Photoshop displayed a notification saying that there is a problem with my Display Driver, and that I should re-install it.
I re-installed my graphics driver, tried several different versions too, re-installed Photoshop, did a clean uninstall (with the help of the Adobe Clean tool) and re-install, but none of these actions helped.
While I was in safe mode (for cleaning up my GPU drivers), I launched Photoshop and realized that even though it told me that there was an error with my drivers, it would work just fine, without crashing after executing a few actions.
I also checked the Help -> System Info dialog for possibly obtaining additional information about the error, but the only relevant thing I can see is 'The GPU Sniffer crashed on XX/XX/XXXX at XX:XX:XX'.
I find this weird, because when I manually run the sniffer, it simply exits after printing 'snifferStart="XXXX-XX-XX_XX:XX:XX"'.
The last thing I tried doing was renaming sniffer.exe to something different.
This resulted in Photoshop re-enabling the GPU Settings box (but obviously saying that there is no GPU detected), and getting rid of the weird crashes.
However, it also resulted in various other glitches, like the main view not updating, the layer previews not properly working, etc.
Finally, I should note that I tried using both Photoshop CS6 (which I initially had installed), and a trial version of Photoshop CC.
My system specs are the following:
OS: Windows 8.1 (64 bit)
RAM: 16GB DDR3
CPU: Intel i5 3570K
GPU: AMD Radeon R9 290
Secondary GPU (Onboard): Intel HD 4000 Series
Currently Installed Photoshop Version: Photoshop CC 14.1.2 (x64)
Any help would be greatly appreciated.
Thanks in advance!

Answer 1

I noticed the same problem if I had my two R9 290s in Crossfire mode. If I turn off Crossfire, I get no error.
HOWEVER, as I have just upgraded from 2 GTX580s, and I do a lot of professional digital painting, I noticed using my Wacom Intuos5 (I usew the Cintiq 24HD with GTX580 at work), there was heaps of lag in painting with a standard brush. If I just did a slow stroke, the 'paint' would be lagging behind the brush 5-10mm onscreen. I tried setting the 'Use Graphics Processor' down to Normal and Basic, and it got worse. I turned 'Use Graphics Processor' off completely and there is no real discernible lag, feels very natural as with the Nvidia cards. However, because this is turned off, I loose any GPU 'accelerated' advantages like animated zoom etc.
