Ive been running a single gtx980 and a ROG swift for the past few months. Its been great, but I was planning on upgrading to a second SLI at some point to always hit a constant 144fps in games at 1440p. Well now that the gm200 is near, should I wait for that and stay with the single card solution, or has SLI scaling come a long way and it is worth it now to buy a second card. (I havent used SLI since the 400 series and it was the worst experience ever)
