Hi, I'm working on a new system and I'm curious to know what GPU complements the i5-3570. I was considering the GTX 670, but I heard the GTX 7XX series are cheaper if not the same price and significantly better, then one raised the issue of the R9 280X being the new go-to card. Would anyone care to make recommendations? I'm seeking to play games such as CS:GO, League of Legends, Blade and Soul, and other titles that will be MMORPG based.
