Hi. I currently have this motherboard ( http://www.asus.com/Motherboards/P8P67_PRO/ ) and I'm planning on getting a XFX Radeon R9 290 ( http://www.pccasegear.com/index.php?main_page=product_info&cPath=193_1575&products_id=25613 ) and am a little confused about whether my motherboard would support it. The GPU uses PCI-E 3.0. Will it? Thank you.
