4 out of 5 eggsWorks with Ubuntu, Steam

Pros: Fast enough for Steam games
Moderate price
Quiet
Works with Ubuntu 14.04 with no extra drivers
Works with Steam (on Ubuntu) with no extra drivers

Cons: Large size
Bracket blocks port on my motherboard (*this is why I took one star off the review*)

Other Thoughts: I bought this to go in my desktop PC running Ubuntu 14.04 in order to make Steam games work better.

Installing it was difficult because of its large size. I had to move hard drives and reroute cables inside my tower. A metal bracket on the video card blocked the case-audio port on my motherboard (an ASROCK H61M/U3S3), which is too bad because the bracket doesn't need to be shaped like that.

I was worried about installing drivers to make the video card work but no, it worked immediately. Having it installed means the integrated graphics on my mother board are disabled.

I don't do a heck of a lot of gaming but this card transformed my experience with Cities: Skylines from uselessly slow to silky smooth. For my needs, this card works quite well. I have only had it for a few days so far, so I can't comment on long-term function.

5 out of 5 eggssatisfied

Pros: I purchased this card for my last computer a few years ago . when I did a new build it was one of the few things i kept . No its not a new as everything else and maybe it is out of date by today's standards . And that's ok . It works , it works very well . I wanted to play games with good graphics and decent frame rates . I didnt want to have to go out and by a six hundred dollar ps4 to do it . I am really happy with my choice . I'm not a hardcore ( need three monitors and my moms basement ) type of gamer . But being able to play crisis 3 at max settings without issues really gets my geek on . and my buddy that bought the ps4 , hes kinda wishing he'd just upgraded his computer as well . Thanks Asus . my next card will be an Asus as well

Cons: When i put it in my new computer I broke to of the blades off one of the fans . Bummer . It doesn't seem to be an issue . I figured it would caus a balance problem with the rotation of the fan or something . nope and no heat problems . But I know its broke and it bugs me . Cant find a replacement for it either .

2 out of 5 eggsDont know what to say

Pros: Runs everything in my gaming spectrum efortlessly....as long as it works.

Cons: Cons, really? Do I have to repeat what everybody has already said?

Other Thoughts: Build: Intel Core I5 4590, MSI Z97 SLI mobo, Asus GTX660 DirectCuII, 4G generic RAM. 550W Cooler Master PSU

Ok, first of all, I live in Cuba, bought all of the above except the RAM on newegg through a friend in the US. VGA card was 20$ more expensive so I think 2 years have been enough on people catching up with the "faults" on this card, sorry I didn’t realize sooner. That’s just to state that RMAing is out of the question for me.

So, I receive my package and I go on as happy as a school kid to mount the rig, I asked a much more experienced friend to help me out on that. Everything went ok and he left leaving me with the menial task of installing a fresh OS. I do so, install everything in both Asus and MSI installation Cds. So far so good.

As a proud new owner of a (average) gaming build I go on and ask W7 to give me its experience evaluation, and then all went to….

Got BSOD with no video output whatsoever, thought was a random problem and restarted, to spare you the details and summing up on that day I got several other BSODs, random system freezes and a gazillion cute messages of “graphic driver has recovered”, blah, blah. If you have done any research on this card sure you have seen this before.

Given the budget, why did I get a NVIDIA graphic chip on an ASUS card?, simply put because don’t like to pay 20 o 30 bucks just to have a EVGA which is basically the same, or even more difficult to keep cool in this weather, and I just heard tons of "complaints" about R9 270 cards, so I thought was a smart decision.

Next day ran frantically to the Internet merely to find out that this is a common problem with this card, thought that would be good since you good guys should have an easy fix for it. Bazinga! Not in your lifetime!. Tried all advices, from downclocking to registry editing, that only avoided the BSODs but still kept having numerous system crashings and kernel issues popping out of whatever game I was in the moment. Did more digging and applied the least recommended, revert Nvidia screw-driver to a 305 version and shut down most W7 graphics options including Aero, that was the day before yesterday. Guess? No more problems so far, yesterday loaded a good 2hours gaming session on several average-demanding games with no issues, temperature didn’t even went above 50. G willing it will keep like that.

The thing is: is not Neweggs fault, its not ASUS fault. But what the…do the people from Nvidia do for a living?? Don’t you have any kind of back feed?? Im no computer genius but this is clearly a software engineering problem, how is it possible that your newest drivers sets, (and the one included with the card) not only do not fix the problem, but make it worse. Cant you come up with a patch-like thing or something? I had a very sad night sleep thinking I got stuck with a gorgeous but worthless piece of plastic, and right now I have fingers and toes crossed for not having any more serious issues with this card.

1 out of 5 eggsUnstable in Windows 7 & 8

Pros: None

Cons: This card is not stable. BSOD in Windows 7 & 8 64bit. I have worked with Microsoft tech to identify issue and all points back to card. Have installed multiple drivers from Nivida and all the same. Also, the screen flickers or blacks out for a second. Sent Asus a open ticket email and no response.

5 out of 5 eggsSweet spot card

Pros: I've had this card for roughly 7 months and everything has been perfect. I mostly play lol, smite and various other steam games on this card and rarely do i ever use the boost. Since this card is now 2 gens old its price is extremely low.

Cons: it's 2 generations old which isn't a bad thing but you're better off buying the 960 or even the 760. Buying this card in 2015 would not be a good idea seeing as though the newer generation cards will have been made without any of the 660s flaws. They will run quieter, use less power and have newer grade hardware.

Other Thoughts: The 660, 760, and 960 are all mid level gaming cards and anything stronger can be a waste. remember to be patient and don't jump at discounts. read reviews and make sure you know that your buying a old card.

5 out of 5 eggsAn Incredible GPU

Pros: Beautiful design, even two years later
Nice price
Long lasting design from Asus and NVidia
Excellent cooling

Cons: it's two generations old, which in the GPU books makes it a dinosaur.
comes with no extras. all the power adapters, vga adapters, stickers...nothing but a cd, manual, and the card. which can also be a positive but I have found use for those things before.

Other Thoughts: Let's be honest, this card didn't break any records in it's hayday. Everyone was buying the 660ti, and this little guy was forgotten about. But I have had this card for two years and it's run everything at ultra or near ultra settings. Crysis 2, WoW, ESO, CSGO: they all ran flawlessly. With the mail in rebate, this card is a really good deal at $120. It also overclocks really well. If you don't have the extra money for a 960, this is a great card and will last you a long time.
It's been retired for a 970, this review is just a swan song for a great video card that I know a lot of my WoW friends still use.

5 out of 5 eggsGreat Video Card

Pros: Bought this video card to run on my new build PC and it's running great, low noise great and fast resolution. I'm running the new AMD FX-9590 Vishera 8-Core 4.7GHz on the MSI 990FXA-GD80 V2 Motherboard with the G.SKILL Ripjaws X Series 16GB DDR3 SDRAM DDR3 2133. Setup was easy and no special configuration needed it.

Cons: Runing for less than a month but so far no cons...

Other Thoughts: I read the reviews and just hoping to get the rebates I have just submitted, hope not to get any surprises...

5 out of 5 eggsAfter a year, still like brand new

Pros: bought this card around February of last year worked great then and still work great now, i never tell myself: "boy i wish i had more power to run this game" in most situations the 660 can run on high settings. now even better paired with the 8350fx by AMD

Cons: none really, it does what is made to do

Other Thoughts: i may buy another one soon, they arent too expensive and it will be nice to have that extra boost

5 out of 5 eggsSolid Card

Pros: Bought this card for a new PC build and so far has performed great! It's very quiet and has delivered great resolution and frame rates. Love being able to plug HDMI into it for use with my TV. Was happy to see it put out a great looking 1080p display. It has great customization options in the drivers to help get the picture set up right if it doesn't automatically line up (which it did perfectly for me) So far I haven't gotten too involved with the games; mostly just WOW, Sims and The Forest which all look awesome on max settings. Overall very happy with this card and that I got it on sale around the holidays.

Cons: None so far.

Other Thoughts: Sounds like by price comparison the gtx 960 is a good upgrade for the price so I may end up upgrading in the future but I can't see there being a need to anytime soon.
