I live in Canada, so im looking something that is easy to RMA if things go bad, hence why I picked Asus, Ive heard good and bad from 290s in general, I just dont know if the performance increase is worth the risk of running lower reliability. I do understand that some games dont have multi GPU support, but even then a single 770 vs a single 290, the 290 still wins.
My biggest concern I want performance but I dont want to have to RMA cards after say 4 months, I also heard the 290s run hot, especially compared to the MSI TF 770.
