bystander :
HDMI 2.0b also supports 120hz at 1080p (not sure on 1440p). This is also good for HD3D TV's. And it's simply the new standard. There is no reason to not use it if the uarch can support it.
I responded to another post here about not seeing some cards with the 2.0 option. This is the card I was looking at: http://www.newegg.com/Product/Product.aspx?Item=N82E16814127965&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-Veeralava%20LLC-_-na-_-na-_-na&cm_sp=&AID=10446076&PID=6202798&SID=
Ahh, so 2.0 is standard now? If so, I have no issues 'tall. I saw more expensive cards that explicitly listed 2.0, so I was gauging that premium.
For instance, knowing it does push 1080 to 120hz is a reason it makes sense if you're never running 4k, in gaming or otherwise.
So, long winded "thanks" : P
