NEWS GEFORCE GTX 1660 SUPER

swapped out the slower GDDR5 memory of

the original GTX 1660 for cutting-edge GDDR6

VRAM in the new GTX 1660 Super, and oh,

what a difference it makes. In our testing across

a variety of games, the upgraded memory

pushes the new card well beyond the original

GTX 1660’s performance and closer to the

frame rates pumped out by the $280 GTX

1660 Ti (go.pcworld.com/ro60).

Again, check out our review for more

details, but the Super version is worth the

extra $10 over the original GTX 1660’s price.
