Hi..yes you can..I also had 6990m installed in mine. Got the 680m now.

Thanks! My 6990m is about to die (I just had to reball it) and I think it might be worth trying to switch to NVIDIA.

I want to flash my Firepro m8900 to the 6990m for better gaming performance. Is this still the best option right now? If so, can someone point me in the right directions please?

I am pretty certain that this does not work. I flashed my 6990m so I could use the FirePro drivers and get better performance in programs like Adobe After Effects.

I modified the clocks to match the original 6990m clocks before I flashed it and still got worse gaming performance--probably because the drivers are not optimized for games.

Sorry for the necro, but in case anyone still has this issue, my rMBP came with the LG display and I was able to get it replaced for free by taking it in to an Apple store.

They run something similar to Retina MBP (rMBP) image-retention test on it and will replace it as long as it is still under warranty.

Does anyone know if it is possible to upgrade a P170HM with a 6990m installed originally? I remember reading something about NVIDIA and AMD cards not being cross compatible, but I can't really find any information on google.

I can confirm that this works with the Clevo 6990m. I used the 12.1 beta drivers and I did not have to change any of the Catalyst files.
