If you are asking if they are compatible, than yes, you can use two of them in that board. Thing is, I honestly dont know if it will physically fit. I mean, I dont see why it wont, but I couldnt tell you for sure.
But what kind of cards are those? The one he is showing are the Leadteks which have ENORMOUS HS/F's on them, alot bigger, I think, than the ones in the picture.
The Leadtek's have a massive heatsink, which is what makes them so good for Ocing. The eVGA's are some killer cards, but their cooler just SUCKS! I mean, seriously, look at it compared to the Leadtek one, the Leadtek one if like 4 times as big! Not to mention 100% copper, and the eVGA's are anodized aluminum.
