Hello, As per my previous question i was sure i wanna buy 2 Radeon R9 290X and CF them so i went to buy all components and build this new system!!! When i was looking at the motherboard (ASUS Crosshair-v Formula-Z) i saw it has PCI-E 2 slots!!!! actually all availabe AMD motherboards are PCI-E 2!!!!!!!!!!!! but all new radeon VGAs (7000 and r9 series) are PCI-E 3 graphic cards!!! i am fan of amd and i have not used intel cpu for desktop for 16 years!(i love to hate intel) so i will not love my PC if i get intel one ........................ i wanted to know what should i do?! will this PCI-E 2 issue which all AMD motherboards has reduce my performance? I am very disappointed at the moment by the way!
