Verdict
At $299.00, the GTX 1660 Super costs about 19% less than the $369.99 Arc B580. That $70.99 saving is real money, but not so wide that the pricier card is out of reach.
The Arc B580's 12 GB of VRAM is a 6 GB advantage over the GTX 1660 Super. At 4K or in heavily modded games that extra buffer matters — and it provides headroom as future titles push VRAM requirements higher.
