SpecPicks Verdict
SpecPicks scored MSI Gaming GeForce GTX 1660 Super 192-bit HDMI/DP 6GB GDRR6 HDCP… using a rating × review-volume × price-fit model applied to our editorial and benchmark analysis across the graphics cards category. MSI's graphics cards lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for graphics cards of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions
Is the GTX 1660 Super good for 1080p gaming?
It is aimed squarely at 1080p. The 6GB of GDDR6 at 14 Gbps on a 192-bit interface and the 1815 MHz boost clock give it headroom for mainstream titles at 1080p, which is where its strong user reception comes from.
Does this MSI card support ray tracing or DLSS?
No. The chipset is the NVIDIA GeForce GTX 1660 Super, which is part of the GTX line and does not include the RT and Tensor cores that RTX cards use for hardware ray tracing and DLSS. It does support DirectX 12.
How many monitors can I connect at once?
The card has three DisplayPort 1.4 outputs and one HDMI 2.0b output, so you can run a multi-monitor setup. Digital maximum resolution is 7680x4320.
Is the GTX 1660 Super Ventus XS OC VR ready?
Yes. MSI lists this card as VR Ready, and NVIDIA's VRWorks technologies cover VR audio, physics, and haptics with leading headsets.
What power supply and warranty should I plan for?
Power supply and warranty terms are not listed in this product's specifications. Check the MSI product listing or the manufacturer's site for the current recommended PSU wattage and warranty coverage before you buy.
