GTX 660 SLI better than Gtx 680?

post #1 of 13
Thread Starter 
HI all. What is the better choice. I can buy GTX 660 SLI. Is this better than single and more expensive Gtx 680? For me 2x 660 GTX will be cheaper. Please answer, Thx


Normal GTX 660 SLI . NOT TI !!smile.gif

yes it will be a little better fps wise then a 680 but the mem bandwith will bottleneck and any eye candy will criple the cards..go with the 680 definatly if you have the option..

You mean what eye candy:)? I mean what is better choice for gaming. SLI 660 or single GTX 680?

From sites i see that 660 GTX.

It would be faster in games that have good SLI scaling, but if you get a game that doesn't you will be disappointed. Honestly, the best advice is almost always to get the better single card over trying to SLI two lower end cards. Get a GTX 670 (which is 95% of the performance of the GTX 680 for 75% of the cost) and then if you still aren't happy you can always add another one down the road.

What resolution are you gaming at? Unless you are running multi-monitor, the GTX 670 is going to be plenty of card.

i mean when you turn on aa it will criple your cards..and sli is very good in games..but i have 2 680s and they are great..but in all searousness buy a 680. you will be able to run maxxed out settings with everything turned up with great framerates..i think the 680 would win with all settings turned up. and a 670 isnt 95 percent performance of a 680..i had several 670s and my 680s own them..i would have kept my 4gb 670s if they were that good..but there not so i got 680 2gb sli..and theres no difference in 2 and 4gb cards..dont waste your money..unless your gameing on 3 2560 1600 monitors

I would get a single 680 or even GTX 670. That way you will not have to depend on SLI scaling...

Agree w/Forceman ... the 670 is much better value than the 680. Depending on the individual sample you get, after overclocking, some 670's are faster than some 680's. For example, I'd bet that my particular 670 (which will do about 1365c/7100m) is faster than probably 25% of all the 680's out there ... talking w/both cards OC'd to their max clocks. And no 670's are ENOUGH slower than any 680 that you'd actually 'notice' the difference in the gaming experience with the naked eye.

SLI is fun and everything but honestly a high-end single card is a better option than SLI'ing two mid-range cards, even if the SLI setup has a better FPS/$ ratio. And this is coming from someone who ran Crossfire or SLI for the better part of the past 4 years.

Because of the effect of microstutter, two cards in SLI need to run at quite a bit higher FPS to match the smoothness of a single card. Like, 45fps in SLI is about as smooth-feeling as 35fps in a single-card. Once you take that into consideration, the 'value' of choosing the SLI setup goes down noticeably.

On top of that, you have the extra heat and noise concerns, + the possibility that you encounter games where nV has not yet made an SLI profile for the game. When that happens (unless you hack yourself a solution), you'll have the performance of only one of your two cards.

If I were you I'd choose a 670 thumb.gif

From what I have read a pair of 660s will be a decent amount faster than a single 680. As some people have pointed out the downsides are that some games don't work well with sli and there is less of an upgrade path since anything after sli scales horribly for the amount of price/performance. I would go with a 680 or even a high end 670. You get a better upgrade path, less noise, no SLI issues and a 670 or 680 is more than enough for anything on 1080p

the only 670s i would recomend getting are the evga ftw. asus top or the msi poweredition..everthing else i would pass on..but searously if you have 480 to spend the gtx 680 lightnings are on sale at newegg.com and most cards will do 1350..mine go over 1400 with unlocked voltage..the only thing about the 670 and 680 is about 5-10 frames..but to me thats worth it as im a 120hz gamer.but if your just 1080p at 60hz a 670 will be sufficient.

get one 670... no need to grab two 660.... on 670 is cheaper too... and it will max out anything on a 1080p monitor ... then down the road if needed..then add another one... but by then..u would want a 700/800 series card =)

i have never need for SLI / CF because when the need for an upgrade.. it was better to just sell the current card and go for a new card because the performance of new cards always out perform my current card in SLI and the cost are usually lower as cards are always dropping in prices even when they are at launch.
