Built a new rig less then a month ago and due to some budget restraints @ the time I purchased a 1.25g evga gtx 570 hd superclocked over a 2g 670. Now being about a month later and having the extra cash I'm wondering what would be a better route for me to go. SLI my current 570 or take the card back (which is still within it's 30 day return policy) and grab a 670. I'm not overly impressed by the 570's performance as it is and believe it should, perform better then it does. I'm only on 1 Samsung 2420l Monitor 1920x1080 60 mhz, so the low memory of the 570 shouldn't effect me. I dont plan on running more then 1 monitor in the future, however I may want to upgrade to a higher reso one (which I'm sure the low mem of the 570 would be an issue) However this is not in my near future. I'm simply looking for better performance on my current set up. I only play Diablo 3 and WoW and have dropped to as low as 45 fps on diablo and 30 fps on wow in intense gameplay scenarios.
