Digit-Life posted a review on the ECS GeForce 8600 GT

This article is quite brief. It is, so to speak, a mini-review of a rather peculiar graphics card. It draws attention, because despite being marked '8600 GT' it operates at increased frequencies. Mind you, its shader unit works at a whopping 1566 MHz! And as you know, an overclocked 8600 GTS card has shader unit working at up to 1440 MHz. This fact alone makes this graphics card very attractive. In addition, it has a noiseless passive cooling system, which is another peculiar feature.
