Now that we know that the cost of entry for AMD’s Navi-based Radeon RX 5700 series will be $379 and above, there are no doubt many of you who were holding out hope for a card that is priced in the sub-$300 market and are now looking elsewhere to fulfill your gaming needs.
Today, we’ll be looking at exactly such a card from our friends at GIGABYTE: The GeForce GTX 1660 Ti Gaming OC which retails for $299, a slight increase from the base MSRP of the reference GTX 1660 Ti which is $279.

Looking at the specifications, we can see that the Gaming OC offers a 90 MHz factory overclock compared to the reference GTX 1660 Ti. This is a roughly 5% increase in maximum clock speed. That increase should help justify the price increase, but that alone will likely not be enough to warrant a recommendation.
EDIT: corrected % increase in clock speed from 11% to 5% vs reference.
GIGABYTE GeForce GTX 1660 Ti Gaming OC Overview
Now that we’ve gone over the specifications, let’s take a look at the card itself to give you an idea what you’ll be getting.
Starting with the box, you can see the normal GIGABYTE styling on the front, along with the mechanical “bird’s eye” the company likes so much. On the back, we actually get a nice look at the cooling system, and of course, a look at the card’s RGB capabilities.
Taking a look at the card itself, we can see it features a triple-fan cooling design, along with a full-cover backplate which is made of plastic and extends into the plastic fan-shroud at the back. Overall, it’s a nice looking design, although we would have preferred to see a metal backplate, especially at this pricing.
The card measures 280mm (11-inches) long x 116.7mm (4.5-inches) wide, and features a standard dual-slot design. It is also powered by a single 8-pin PCIe power connector, which is the same as the reference board. The PCB itself is actually shorter than the cooler, measuring only just 225mm or just under 9-inches. It also features 4+2-phase VRM.
RGB-lovers will be happy to know that the GIGABYTE logo on the side features full RGB illumination and the card works with GIGABYTE’s RGB Fusion ecosystem, so you can sync it with your motherboard and other GIGABYTE/AORUS products.
For I/O, you’ll find 3x DisplayPort 1.4 and 1x HDMI 2.0b ports.
The fans themselves deploy GIGABYTE’s patented “Alternate Spinning” technology. This allows the center fan to spin in the opposite direction, which is claimed to create a smoother, less turbulent airflow path and provide improved heat dissipation. Like many other cards in the market today, the fans will also remain off when the GPU is idle or not under stress.
The heatink consists of three small aluminum fin-arrays which are contacted via three copper-heatpipes, the heatpipes themselves make direct contact with the GPU, while the VRAM, and MOSFETs are contacted by the the aluminum plates which are connected to the fins.
Graphics Card Test Setup and Methodology
All game benchmarks are taken from a 3-run average either in-game or using the title’s built-in benchmark utility. Performance is recorded using OCAT: the open-source frontend for PresentMon, which itself is an open-source capture and analytics tool which supports modern APIs such as DirectX 12 and Vulkan.
For our graphics card reviews, we use a 2nd generation Ryzen-based system with some parts supplied by AMD and DEEPCOOL. Thanks to all who sponsor components in our test systems, as without them it would be very costly to source the components we need.

GIGABYTE GeForce GTX 1660 Ti Gaming OC Overclocking
Using MSI Afterburner, we overclocked the GIGABYTE GTX 1660 Ti Gaming OC even further than it came out of the box. We managed a Core Clock offset of 135MHz (bringing total to 1995MHz), and Memory Clock offset of 1000MHz bringing our memory speed up to 14Gbps. Theoretically, this should improve performance quite a bit, especially in more memory demanding titles. We’ll find out soon enough.
GIGABYTE GeForce GTX 1660 Ti Gaming OC Power and Thermals
Looking at total system power, we can see that at stock the 1660 Ti uses a little less power than the GTX 1070 FE and about the same amount once overclocked. While the 1660 Ti does have fewer CUDA cores than the GTX 1070, it does have a higher clock speed, so the the power draw similarities make sense, even despite the more refined manufacturing process.
That said, the superior cooling capabilities of the GIGABYTE card’s triple-fan cooling system are shown off here, as even while overclocked our temperature delta is significantly lower.
GIGABYTE GeForce GTX 1660 Ti Gaming OC Performance
3DMark Fire Strike and Time Spy
Assassin’s Creed: Odyssey
We test this title using the game’s built-in benchmark utility.
Looking at the above graphs, we can see that at 1080p, the GIGABYTE card does offer 9% more performance on average when compared to the GTX 1070 FE. That said, when looking at the 0.1% lows we can see that performance is actually quite a bit worse at 37% lower. This is alleviated once the card is overclocked as it gains a 7% lead in 0.1% lows and increases its overall lead to 14%.
Shadow of the Tomb Raider
We test this title during a 60-second gameplay segment in the ‘Hidden City’ portion of the game.
At 1080p in Tomb Raider, the 1660 Ti offers the best performance at stock, we’re not exactly sure why but we ran the test multiple times to verify the results. Nonetheless, both configurations are very similar.
Compared to the GTX 1070 FE, the GTX 1660 Ti offers 10% more performance on average and absolutely decimates it in 0.1% lows with a commanding 85% lead.
Far Cry: New Dawn
We test this title using the game’s built-in benchmark utility.
Forza Horizon 4
We test this title using the game’s built-in benchmark utility.
HITMAN 2
We test this title during a 60-second gameplay segment in the ‘Santa Fortuna’ map.
HITMAN 2 again sees the GTX 1660 Ti take the lead over the GTX 1070. This time, by an average of 7%, and a further 2% once overclocked.
It’s worth noting that for this title we have the GTX 1070 running in DX11 mode, while the GTX 1660 Ti is in DX12 mode, as that is how both cards performed best and were most stable.
Resident Evil 2 (2019)
We test this title in a 60-second gameplay segment at the early portion of the game in the fiery streets of ‘Raccoon City’ on the way to the police station.
Battlefield V
We test this game during a 60-second gameplay segment of the ‘War Stories’ single-player game mode on the first level of the ‘Tirailleur’ campaign.
Moving on to Battlefield V, we see that the GTX 1660 Ti offers a miniscule 3% performance increase over the GTX 1070 FE on average, but also loses by 31% in 0.1% lows. These results are not unplayable, but there will be a noticeable micro-stutter which some users may be more perceptible to than others.
Tom Clancy’s The Division 2
We test this title using the game’s built-in benchmark utility.
Gears of War 4
We test this title using the game’s built-in benchmark utility.
Wolfenstein II: The New Colossus
We test this title during a 60-second gameplay segment on the ‘Roswell’ level of the campaign.
World War Z
We test this title using the game’s built in benchmark utility.
Closing Thoughts
At $299, the GIGABYTE GeForce GTX 1660 Ti Gaming OC is pretty far from the most expensive GTX 1660 Ti model available, in fact it’s at least $30 cheaper than the ASUS STRIX Gaming OC model, which is also clocked 30MHz (1890MHz) from the factory. So, from that perspective, the GIGABYTE card actually seems like a good value, if you’re looking for a triple-fan cooling solution. That said, the board design found on the Gaming OC is also the very same one used on the GIGABYTE GeForce GTX 1660 Ti WINDFORCE, which is a dual-fan card that is $20 cheaper and clocked slightly lower at 1845MHz. So, we’d imagine that card to perform fairly close to this one, and likely overclock just as well, albeit with marginally higher operating temperatures.
Of course, if you’re reading this review you may be trying to decide which 1660 Ti to buy, or maybe you’re wondering if you should buy one at all. On average, that GIGABYTE card shown in this review performs 6.3% faster than the GTX 1070 FE at 1080p, making it a strong contender as a worthy upgrade for GTX 1060 owners, or folks with even older hardware such as the GTX 970 or R9 290 who don’t want to spend more than $300. That said, there is also the Vega 56, which we’ve not tested here, but should perform similarly, if not slightly better in most cases. You’ll also find models from PowerColor and Saphire that are priced at the same $300 as the subject of this review, and that definitely makes a recommendation a bit harder for us, but we’d still say it’s a fairly decent buy.
With great cooling performance, and rather fantastic overall gaming performance as well as fairly solid overclocking potential, we’d say that the GIGABYTE GeForce GTX 1660 Ti Gaming OC is a solid choice for gamers looking to spend $300 or less on a graphics card for 1080p and 1440p gaming.
