Hypothetically, 3090 XC3 -> 3090 Hybrid FTW would be eligible if they put it up on the step-up? Or no because it's not really a model upgrade? Or I would have to do 3080 -> 3090 Hybrid?
I don't want to be gambling on the Hybrid potentially and be stuck with a card I didn't necessarily want from the get go :(
Here is what has happened "Historically"...
Short answer is no to the first part, and kind of to the second.
Here is the deal... EVGA has not posted all the GPU models for a series on the Step Up, like ever. Your scenario is very unlikely to happen, where EVGA would post multiple offerings (3090 reference, FTW, FTW Ultra, Hybrid, Black, Kingpin and some other variant) in the Step Up program.
Speaking to your question as only an example... The GPU need to be considered an upgrade. If the RAM and or spec (Not counting the clocks) are the same for the 3090 XC3 & 3090 Hybrid FTW might be considered unilateral and not qualify.
However. Say you want to go from a 3090 reference and EVGA has posted a FTW that has a higher RAM count than the reference. Then yes. In this hypothetical scenario you could Step Up if qualified.
Bottom line....
You will most likely only see one, "Maybe" two models of any series in the Step Up program.
You need to do what works best for you.
Just look at this link
https://www.evga.com/support/stepup/ and you can see most of your questions are answered. Including what I am speaking to above. You do not see a list of five models in one series as options to Step Up to.
Good luck and have fun!
