Not sure about the SE, that would be question for Sapphire directly if you contact their support.
They are all similar. However, I understand the orange air cooled Toxic to be the best binned, as it has a boost rated up to 2500Mhz. Out of all of them, this would be my preferred choice.
I do not believe any of them are XTXH models though, that includes the orange Toxic.
Thanks, may hang on a few weeks to see if the rumoured 6950/6960 brings anything worthwhile. Send if any AIB versions come out, may be wishful thinking but given the 3090ti isn’t that terrible value (relatively to what prices spiked to last year) hopefully the new GPU comes in close to what XTXH AIB cards are priced now to close out this generation.
