Wow, you're right! I assumed since the FE cards weren't listing this block in the compatibility tool, that the tool just hadn't been updated. But I looked through and about 1/3 of the cards are - but mostly the "smaller" brand cards. Not ASUS, MSI or GIGABYTE, but rather brands like Zotac, PNY, Manli, Leadtek, Galax and Gainward. Which kind of sucks because those cards are a.) mostly not available in the US and b.) super over-priced. I think I'm just gonna stick with my SLI 1080TI's for another year until the 4000 series hits and maybe I can get something there.
