Hello all. I have a R9 270x 2gb radeon graphics card.

I've read on many of the other threads that a gaming GPU has minimal impact on video production.

Hence I have a few questions:



1) For 4k and 360 video is a discrete graphics card recommended (especially the modern 2-16gb PCIE cards) or is the recommended 128mb card sufficient?



2) Is there any real impact using a GPU or can one simply use integrated graphics?



3) Can I use the 2d Power director benchmarks as a good indicator of how while a particular CPU/GPU will perform in 360?
