A month and a half ago we published a review of the GeForce GTX 690, Nvidia's current flagship grpahics card with two GK104 Kepler GPUs. Getting our hands on a single GTX 690 was already quite the challenge, getting two of them proved to be next to impossible, that is how rare the cards are.
We recently had the chance to test a real-life configuration that actually uses two GTX 690s, assembled by a local Dutch store. They lent us their Ammo Box III gaming PC, from which we "borrowed" the two GTX 690s and put them on our standard testing rig.
This review will focus on the performance you can expect from combining two GTX 690s. If you are considering spending about £1,700 on two of these bad boys, keep in mind that the TDP of single GTX 690 is 300 watts. Double that, add the other PC components and you're easily at 800 watts. Planning on overclocking? That adds even more. We therefore recommend a PSU of 1200 watts for a setup like this. We used the Cooler Master Silent Pro Gold 1200W, which proved quite capable of supplying the two GTX 690 with enough power for our SLI test.
