OK here is where I am at, I'm currently looking for a short term solution. I just recently got into the PC gaming world, and when putting together my system I was running a rather tight budget. So I went and bought a EVGA superclocked 660, but quickly found out to kind of chokes on certain games when maxed out.
Now I have been doing my research here and there, and am fighting an internal war on getting a gtx 770/780, or just paring up my card with another 660. This is only a temporary solution as I am waiting on the 800 series cards, I hear are to be released in 2014. so Just wondering in your opinion what may be a better short term option, and a possible fix to some of my issues xD.
I have filled out the form thing I found on the forum, and I hope I did this right im not used to dealing with forums.
APPROXIMATE PURCHASE DATE: With in the next week or so
RANGE: Budget isnt really the question here.
USAGE FROM MOST TO LEAST IMPORTANT: Mostly for my Gaming PC, I got metro last light with my graphic card upon purchase and really want to play everything maxed out. However when I do on my current EVGA Super clocked 660, my average FPS is in the lower 20's and I suffer horrible micro stutter.
660 sli will yield you better performence then the 770 and slightly better performence then the 780, with that being said, sli consumes more power, can cause overheating, and is badly optimized for some games.
if i were you, i would sell my 660, get a 770, and maybe in the distant future get another 770.
search the web for performence with 660 sli, and 770\780, to get more accurate information about performence.
As stated you could try to sell the 660 and get a 770. However a SLI 660 will get you a little above the performance of a 770. Sure you will have more heat on the to pcard, however I have been SLI with 560 and havent had any problems, all known games have a SLI profile up to date that gives you almost the double of performance of 1 single GPU.
I would say to choose the most budget option. a 770 (here) costs aroudn 400€, a 660 costs around 200€. Making 400€ also. However if you sell your 660 you will loose a bit of € ofc.
Try to lower details to high without physx in metro last light and see how it goes. 660 is a good card, I think its on pair with a 580.
