I want to upgrade to a GTX 670 and possibly SLI another on later. Can my Corsair HX750 handle that (along with the rest of my setup) or should I get an 850 watt? I want to leave some 'headroom'. Will there be a bottleneck anywhere?

I game BF3 on Ultra settings.

Current setup:
Intel i7-3770K CPU
ASUS P8Z77-V Pro Mobo
Corsair 2x4GB Vengeance
EVGA GTX 570
128GB Kingston SSD
2x 3TB Seagate Barracuda HDD - RAID-1
Corsair H80 Cooling
Corsair HX750 PSU
Corsair Graphite 600t Case
Dell U2412M 24" 1920x1200 display

Thanks!

The HX750 would be enough, even for SLI 670's.

And no, no bottlenecks.

The corsair HX750 can actually output 900W, so you'll be fine.
