    Great Product for the Money

    I bought this card to replace a defective Rx 580 that ran hot and had driver issues from the first day I got it. The Gigabyte GTX 1660 ti is great. Was easy to install just stuck it in the slot and updated to latest drivers and was done, almost. I did download the AORUS OCing tool and ran a scan with it. The oc was +270 over base clock which is amazing and all I had to do was run the tool, No knowledge needed. Has stayed cool and is quiet couldn't ask for anymore. Would recommend this product to anyone looking for a Good priced GPU that will run +60 fps on most all titles.

    Silicon lottery is a win!

    Games are butter smooth! You don’t need the most expensive model of card for it to be great! That said I felt the crunch of my over all build so I was looking for a cheap 1660ti.. Gigabyte Gv-N166TOC-6GD met that need and then some! This model does only have 1 heat pipe on the cooler but it’s still ok!!! I played overwatch 140fps 62-66c and 65% fanspeed on epic settings on a 2560x1080 monitor paired with i5 3570k (still waiting on new cpu and nvme ssd)I must have won the silicon lottery because right from the manufacturer website my model is supposed to be 1800 boost and 1770 base reference, m

    Great upgrade from a 1060 3gb card. Quiet, fast and cool.

    This was an upgrade from a MSI Gtx 1060 3gb card. I figured for the sub $280 price it was a 40% performance increase. SOTR runs at 80 fps avg in my rig.Ryzen 2600x16GB RamMob msi B450m bazooka v2Seasonic 520 wattFractal mini cIt was smaller than the Msi 1060 card and fit perfectly in my m Atx build.Card is super quiet and runs 29 celsius on idle and 67 when loaded.I'm glad Gigabyte makes a great card and figure it will last me for a while unless RT is mainstream. I've had zero problems upgrading the drivers. I did not overclock my CPU or GPU as well.

    Bang for your buck

    pretty damn good card for the money, but now that the "super" models are out I would suggest getting those instead. much more bang for a little more than the cost of this card. If this is all you can afford though, then this is a damn good card and my games look incredible. I can max out most games at 1080p with a minimum of 60fps. More demanding games, however, tend to dip down to 50 (looking at you rust), but I feel that is more of an optimization thing. A lot of really great looking games run much higher than 80fps. Games that are well optimized often breach 144 fps to keep up with my monit

    Great card

    The 1660Ti is on par with the GTX 1070, arguably better for upcoming games because of the newer architecture. Plays modern games at max settings easily at 60+ fps as of mid 2020.This particular cooler from Gigabyte is a budget option, but it looks good ( black and gray color, has a backplate) and works well too. The fans only turn on when you start playing games.I can't say if this card is powerful enough for future games due to the rumored specs of the upcoming consoles, but I'm confident that it would be okay for at least a couple of years.

    Great card for a great price/overclocking+

    I swapped out my GTX 1060 3gb with a Gigabyte GTX 1660 TI 6gb which is an excellent card & brand. I can overclock it & get 2000hrz core clock from its 1800hrz. This card overclocks its overclock like I've never seen a card do before. For amid-range card under $300 with tax you can't beat it. Yes the RTX cards are great, but not a lot of games support ray tracing & the other it offers plus an extra $70 plus tax it cost like $100 more. So paying a little over $290 with tax is the smarter since than pay almost $400. Plus the RTX uses more watts & need 2 power supply cords. The 1660 TI uses 1 six

    Amazing video card

    I have watched reviews about this video card saying it is better to skip it, that the one to get is the 2060 and I agree; however, for anyone building a new system on a budget, they can't go wrong.I have a 1060 3Gb and recently built a new computer for my wife, and because of budget I thought about picking the 1060 6Gb, but after some consideration I went with this one, I am very surprised with the performance!It does not get hot and it is not audible at all.Her games are always around 30% higher FPS than mine.Now that nvidia is releasing their new SUPER cards and AMD is coming with the 5700s,
