Summary: No issues whatsoever. Plays nice with the Gigabyte Intel Z77 LGA 1155. I play Planetside 2 on Ultra with this, 16GB of RAM, 3570k at 4.4, h80i cooler. I like it because the GPU is already OC'd and made to run that way.
Summary: I installed this in about 10 minutes in my Dell XPS 8300. The card was MUCH larger than my old card, so I did have to do a little creative cable placement in order to get it in. It would have been a hard job if I didn't have small hands, but that's more telling of the size of my computer case then this card. If you have huge hands, you may want to find a nice lady friend with delicate hands to install this card in a small case.
Summary: On first look, I worried about how the fans were mounted to the heatsink. I was used to seeing a complete shroud around everything to give the card a more sturdy appearance and feel. Not a problem. The fans are sturdy and shrouded individually so you don't have to worry about cables or handling messing up the card. It is solid and runs great.
Summary: This quite card loves speed, runs quite and FAST, I run tests and it shines OC the GPU to 1202 with ease.. over 6000 on mem speed... Its not a 660 FYI, its a de tuned 670...and it comes OC from GB, and they upgraded the entire card over standard 660 TI.. new PCB, better components..
Summary: Great performance for the money if you want an nVidia Card. The large twin fans efficiently cool the card even when pushing the card to the max. Over the course of a few hours, my fans made some noise. Noise is the only reason why I didn't give this card a 5 star. Since this card is already overclocked, I wasn't able to manage much more higher OC settings while providing stability.
Summary: I bought this for my Dell XPS 8500 to upgrade from the gt 420 it used to have. It says it needed a minimum PSU of 450w and the Dell has a 460w. The card works, however, my computer is 3 years old and I believe the PSU has degraded to less watts. Also, this card is overclocked, meaning it draws more power. Therefore, if you want to prevent crashing when playing demanding games that push your card to the max, upgrade your PSU.
Summary: This is a great video card. Gigabyte normally doesn't get the press that other manufacturers do but this overclocked card works perfectly. The oversize fans are quiet and keep everything cool. I've bought similar video cards by other manufacturers and in one case, I had the fans seize up multiple times, forcing me to RMA it. I would highly recommend this card and this manufacturer. This specific cooling solution works very well.
