ASUS GeForce GTX 680 SLI Review

Test Setup »


NVIDIA launched its newest, most advanced GPU, the GeForce GTX 680, on March 22. The card wiped the floor with other single-GPU cards, but there's a lot more to it than its performance, so before you proceed with the GTX 680 SLI review, please make sure you've read our NVIDIA GeForce GTX 680 Launch review, because we took the pains to explain a lot of new concepts introduced by the GTX 680, in detail.

The GeForce GTX 680 can pair with up to three more cards of its kind, to step up performance to unprecedented levels. We got two cards to run in 2-way SLI mode, today, thanks to ASUS. We wish we had this in order yesterday, but our shippers took a hollow-point to the knee. We also got a hold of the latest GeForce 301.10 WHQL drivers, and put both the 2-way SLI and single-card through our test suite, driven by them.

NVIDIA surprised us with its US $499 pricing, which beats competition heavily at Performance per Dollar. It also drives the price of GeForce GTX 680 SLI under US $999. In this review, we will evaluate the performance of GeForce GTX 680 SLI, and compare it with standalone GeForce GTX 680, and other contemporary graphics cards, including dual-GPU cards that cost well over $700. The performance figures should give you a rough idea if two GTX 680 cards in SLI are sufficient for gaming at very high resolutions.
