right now im running a low-ish mid range (q6600, 4gb ddr3, 7850 1gb) PC and i want to upgrade, and i got 2 choices- either i buy a new i5 3570k, a new motherboard and some more ram OR I can buy a new KFA2 GeForce GTX 680 LTD OC V2 for approx the same price as the cpu, mobo and ram.. The question is, would i get better performance in games by swapping the CPU and adding some more ram (i`d stay with the 7850 in that case), or by upgrading my gpu to the 680 and staying with the ancient q6600. Keep in mind I`m talking about games, no rendering or whatsoever. and maybe if someone knows, why is the KFA2 GTX680 so cheap ($404) compared to the other 680`s (starting $488), maybe because i`ve never heard of such brand ''KFA2'' ?
