👍 Pros
- Factory boost clock of 1830 MHz delivers measurable performance above reference GTX 1660 Super spec without any manual tuning.
- 6GB GDDR6 at 14 Gbps effective speed provides strong 1080p bandwidth headroom for texture-heavy titles.
- Dual-fan zero-RPM cooling keeps thermals controlled under load while remaining completely silent at idle.
- All-metal backplate adds structural rigidity to the PCB and prevents GPU sag in horizontal builds.
- Single 8-pin power connector requirement keeps compatibility broad — no modular PSU gymnastics needed.
👎 Cons
- No hardware ray tracing support — this is a Turing-architecture card without RT cores, unlike the RTX 20-series siblings.
- 6GB frame buffer becomes a constraint in 1440p gaming as texture budgets grow in newer titles.
- DVI output is increasingly legacy — multi-monitor setups with modern displays will compete for the single HDMI and single DisplayPort connection.
- The SC Ultra factory overclock, while real, is modest enough that it won't be perceptible in most frame-rate comparisons versus reference clocks.
Frequently Asked Questions
What PCIe slot and power connector does the GTX 1660 Super SC Ultra require?
It uses a PCIe x16 slot and requires a single 8-pin power connector. Total board power is 125W, so any mid-range PSU (450W+) handles it comfortably.
How does the 6GB GDDR6 frame buffer hold up at 1080p and 1440p?
At 1080p, 6GB is more than sufficient for virtually every current title. At 1440p, texture-heavy games can push toward the buffer ceiling — you may need to dial down texture quality in the most demanding games at that resolution.
What display outputs are on this card, and what's the maximum supported resolution?
The card offers DisplayPort, HDMI, and DVI outputs. Maximum supported resolution is 7680x4320 (8K), though gaming at that resolution is not within this card's performance envelope.
Does the EVGA SC Ultra overclock push meaningful gains over the reference GTX 1660 Super?
Yes. The SC Ultra's 1830 MHz boost clock is a factory overclock above NVIDIA's reference 1785 MHz spec — roughly a 2.5% uplift out of the box. EVGA's precision boost algorithm also allows further manual overclocking headroom via Precision X1.
Does this card run cool and quiet under sustained gaming load?
The dual-fan cooler keeps temperatures well within spec under sustained load. Fans spin up audibly under full load but remain reasonable — they also stop entirely at idle and low loads, making the card silent during desktop use.
