gtx 660 sli vs single better card

post #1 of 14
Thread Starter 
i currently have one msi gtx 660 and am going to upgrade next week. i am thinking of buying another one or possibly 2 for 3 way sli. i have got good results with my one card overclocking and decent game play on high-ultra settings. i figured 1 or 2 more would really enhance my system. do you guys think i would be better of just spending the roughly $400 on a single better model card or would 3 gtx 660's out perform a $400 card? thanks for any insight.

multiple sli produces diminishing returns and ups power consumption a lot. The 660 is an older card, so it can be had used. Bang for the buck wise, a second (but not third) used 660 is probably the best play, IF your system can handle it without modification. If you wind up needing a new PSU, MoBo, or even CPU, that could all change radically.

Without full system specs there is no way to know that, and therefore no way to answer. i suggest using the "rig builder" button on the upper right part of the page to input your system.

Personally I would go GTX780 or a 290 when the prices come back down. Both are A+ cards and really goes back and forth in terms of game performance.

On one hand, adding a single GTX 660 for SLI will be a lot of bang for the buck and will nearly double your performance. I bet you could find a pretty good deal on GTX 660 as well. Going with three cards will not triple your performance (its kind of like having too many chefs in a kitchen) and for that kind of money I'd just start over with a better single GPU.

Based on these specs, a second 660 is definitely the best bang for your buck option. Though, if you want simplicity, I would personally recommend a single card. With a $400 budget you could get a pretty solid card (GTX 770 or R9 280X at current prices).
