A quite powerful CPU and/or GPU is required to be able to stream at 1080p and 60 fps. Specifically it seems that Chrome has a very hard time in this mode using HTML5 and that Flash usually gives a better result. .
GTX 670 to 1080 is a gigantic upgrade. Don't get too bogged down in synthetic benchmarks. Just play some games and crank those settings up. (14 minutes ago)

@docLEXfisti: A very good GPU, should last you a while. Hmmm in terms of benchmarks, try 3dmark, Catzilla, unigine Superposition, unigine heaven, unigine valley, FurMark and Star swarm stress test. (1 Hour ago)
the increase in GFX power is acceptable (2 Hours ago)
before I had a GTX670.... wanted to go for a 1070, due to only EUR 30 more, I went for a GigaByte GTX 1080 (2 Hours ago)
@docLEXfisti: what did you order? (4 Hours ago)
my poor graphics card is on the brink of death, ordered a new one... any cool benchmarks I should try out apart from FFXV? Thanks for advice (4 Hours ago)
