so i built a new computer, has the 2500k cpu, asus gtx 570 with dcuii, 950 watt psu, asrock extreme 4 gen 3 mobo, corsair vengeance 8gb ddr3 CL9 1600 ram, ocz vertex 3 ssd. ive been saving up some extra money to get a second gpu for SLI. i was just wondering if theres anything thing else i should save up for. like if i should save up for an ivy bridge cpu or better ram. or should i just get another gpu and will two gtx 570's with the i5 be able to handle most games with everything maxed out until the end of 2012? thanks for any help!
