5 out of 5 eggsGreat Card While I Used It

Pros: Was a great upgrade form my 500 series I was using.

Cons: Nothing really, Nvidia has always treated me well when comparing cost to performance, though with so many levels in each series (660, 670, 680...) it can be confusing picking the one that's right for the life of your build.

Other Thoughts: Still a decent card, but I've since moved up to the 960. If you've got the money to spare, I would even recommend going to 970.

2 out of 5 eggsready to sell it

Pros: Seems fast.

Cons: Nearly daily Windows Kernal Driver errors. I bought this for a business system and haven't even had time to try out any games yet. It causes simple programs like Photoshop and Google Earth to crash constantly. I don't have time to get all the details and start a support file with ASUS, Will be cheaper just to get a new on and hock it. What's with the 30-day return window for electronics? Took me more than that to find the time to build the system as it was.

1 out of 5 eggsDead within a year

Pros: can play many games on ULTRA graphics. Very smooth... when it works.

Cons: This card was working fine for a couple of months until it started crashing whenever i was doing the simplest things.
Ive tested the video card on 3 builds and all the same issue. When I would play video games, watch movies/videos or simply surf the internet, the video card would crash. It would say the video card stopped responding. I also tried re building my machine, re installed windows and reset my bios. Same issue.
I tried RMAing this card because it is still under warranty. I paid 20$ for shipping they received and immediately sent the card back to me (received the card in 4 days, sent it back within 2 days) saying there was nothing wrong with it. I tested it again and the same issue is occurring. I called tech support explaining that nothing was done to my card and the same issue was happening. The lady put me on hold for an hour and told me she has escalated this to the highest level and they will contact me within the next day or so. I called 4 days later to check on the case since no one called me and the lady on the line said they closed my case and there are no record of my case being escalated. This is very frustrating and I don't understand why no tech worked on my card, especially since it is under warranty.

Terrible customer service. Not sure why nothing can be done if my card is under warranty.

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 .
