It would be nice to think this, but of them:
- TUF has dual BIOS too
- Reviews have shown no appreciable difference between TUF and Strix cooling (actually, the only one with a direct comparison reckons that Strix was worse off - really hoping for a better showing from GN or someone I can trust a little more)
- ASUS had no way to bin chips at the start, and so far we've not seen any evidence of this
So yes to third 8-pin and the onboard fan headers? Yay...
And please note that I say this as someone queueing for a Strix (and having only some regret I didn't try for a TUF - would have probably had it by now, and it seems to be high on the bang-for-buck scale).
