GTX 970 SLI vs. GTX 980 Ti SLI vs. R9 390 Crossfire?

[TheMailonG]

Hi guys, everybody is saying that a R9 390 beats GTX 970, that's a refresh not a re-brand, that 8GB is better for 3D Rendering and Video Editing (my main purposes) and etc, etc, etc, but there are benchmarks that shows SLI GTX 970 beating Titan X, with single 980 Ti or 980 (and even a single overclocked 970) very near it, and I'm afraid AMD have worst drivers, and have less features and worst compatibility, bigger temps and everything else 'cause I hadn't good experiences with AMD products (from CPU's to GPU's).

I like the possibility of having a GTX 750Ti dedicated to PhysX, and I want to upgrade futher (I will start with a single card).

So, what is best?
GTX 970 2-way SLI with a GTX 750Ti dedicated to PhysX
or
Dual GTX 980 Ti
or
Dual R9 390

Help me guys!

PS: Sorry for my poor English skills.

For raw power and performance twin 980tis win hands down. Depends on what you're doing and at what resolution you're doing it at. Also I don't think you can have 2 970s and a 750ti working together in any way.

Hm, the maxium number of monitors i would buy is 3, at 1920x1080.

For any configuration, twin 980tis leave your other two options in the dust by a very large margin.

You cold try duel 390x/980 for a price point between 970 and 980ti sli.
