You've got a confusion of ideas.
The video card will work fine in any modern motherboard. Its memory is on the card and has nothing to do with your RAM.
As far as an Asus recommendation, the question is what processor you want to get.
This is how you should organize a build:
1) CPU choice
2) Appropriate motherboard choice based on CPU
3) Appropriate RAM based on motherboard choice
4) Any PCI-E video card

That would work nicely with the video card, RAM, and CPU you indicated.
