wow, I never ventured into the 3 or 4 way SLI... brave sole.
Thank you all for the replies.
Would my current system (EVGA X58 E760 Classified motherboard, 12GB Corsair Dominator RAM, Intel i7-950, Intel SSD) be a bottleneck for any reason while playing new titles, such as Battlefield 1 or Titanfall 2? Would using a GTX 1080 with this system present a bottleneck for the videocard?
BF1 pushes my 3770k to 100% pretty much the entire time I'm playing. This is paired with a 980Ti on a 1440p screen. To put it in perspective, a more powerful CPU then yours with a weaker GPU then what you're planning to get and it's maxing out the CPU, so I'd say most certainly you will be CPU bottlenecked in BF1, and by a good amount too.
I've only played on 64 player servers thus far
I will second some of the other comments here towards SLI. I had 680s in SLI and then 290s in crossfire but my best setup to date has been my 980ti paired with a g-sync monitor. Even if the card can't push 60fps it still looks smooth; void of tearing and other issues I ran into with my other setups.
Big difference between the two. Standard vsync doesn't come close. If you think it does, you're just deluding yourself into thinking that if you don't have it, you don't want it.
...as long as you're actually maintaining 60 FPS, no drops below that? Yeah, vsync at 60Hz and G-Sync at 60Hz are the same damn thing. No delusions involved. G-Sync and FreeSync are only useful when your setup won't allow you to maintain your display's ideal refresh rate at the settings you want to run.
I too am running a 980Ti with a gsync monitor and yes, certainly my best setup. That said, the gsync legend that states it makes 30fps feel like 60fps is complete BS. I know that isn't what you're saying, just wanted to put that out there because I know it's been touted around on more then a couple occasions.
