Is my system ok for an upgrade to a GTX 1080?

Just wondering from those with a little more knowledge on specifics if this system would be ok to straight replace the gtx 960 for a 1080? If not which components would also need an uphaul and any recommendations would be welcome too I was also wondering if there would be any worth in running the two cards together with that fancy SLI mumbo I've heard does nice things in the past.

Thanks kindly for your time

Your processor might be a bottleneck, but not much. I’d only suggest the 1080 if you’re gaming in 1440/4K. Also, SLI isn’t worth it. VRAM doesn’t stack, and artifacting is prone.

A single 1080 would be good for that system and yes, avoid SLI as there's less driver support nowadays.

Actually I'm not so sure of that PSU, you may want to get a better unit before upgrading.

i'd agree with AtomicDonut17, but would add, a couple of things.

You can OC your 6600k to offset most of the bottleneck in CPU intenisve games. And also your PSU isn't great. The 1080 needs a 500w PSU, and as most will tell you, you won't draw that much power anyway. However, if you OC you CPU, and get a 1080 i don't think that PSU will hold up. I can't find a review of that unit, but one or two on different models. I wouldn't rate it, and so would suggest a decent PSU like and EVGA GQ/G2 550w and then stick your 1080 in and OC that CPU. you will be good to go for a while yet.

Yeah, I'd run away from that PSU. It's a hec-made with a two-year warranty and we're not even talking second-tier capacitors, but Fuhjyyu/AsiaX-branded ones and ripple suppression just barely in the incredibly lenient ATX specs.
