Hey all, I was looking at getting an MSI R9 270x but noticed a pretty good discount on Newegg Canada- a Powercolor HD7850 for $139.99 (before a $30 USD rebate and taxes). Seeing as how the 270x is a bit less than twice the price, is crossfire HD7850 worth it for the extra money? How are Powercolor's coolers? I'll be using at most 1-2 monitors at 1080p for playing games. Thanks!
