Hey guys. I'm looking to upgrade my Graphics card. I have a GTX 570. I am willing to pay up to $1000 for a damn good card. Not sure which tho. GTX 980 or the 780Ti? Don't know the brand either. EVGA, Zotac, MSI... Any help would be great. Also I play games like Assassin's Creed, GTA, Metro Last light. Games of that nature.
