Strix has higher binning, better cooling, triple 8pin for higher power limit, dual bios and onboard fan headers that are controlled by GPU thermals.
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).
