980 Ti SLI or pascal?

Solution
Depends, now .... if you can wait for the Pascal, would be a nice idea, as it's rumoured it's much faster than Maxwell.
A SLI setup of 980Ti's would be a nice build for 4k also. It's up to you, if you can wait you should, if not than that setup will be great.

That PSU should be enough for 2 980's Ti. .
