My system: AMD FX 6100 6 core, Gigabyte 990fx-uda3, sli-bridged (1st) card EVGA 560gtx 2gb (2nd) card MSI, 8gb Kingston DDR31600 ram, 750 ATX PSU. My question is; are these graphics cards that I have paired are they going to be good enough for all these new upcoming games, and if not what would be a suitable upgrade? Or would I be good for a while with these cards?
