All I can find is mostly 2 slots spacing between cards for 2-way SLI. I did find one board here; http://www.asrock.com/mb/Intel/Z97 Extreme9/index.us.asp?cat=Specifications But I'd prefer another brand and a spot for my stx that is not right in front of the intake of the bottom card. Will probably end up just getting the ASUS MAXIMUS VII HERO but if something is out there with more spacing i'd prefer that... just can't find it! I'm wondering also, if this would actually improve temps more so than just having 2 slots of space... Thoughts? Thanks.
