Even though VVIKOO is new in the business, their GeForce 8600 GT Turbo works very good. The card was rock stable during all our testing and kept the promise of being an overclocker's product. Even though the card is already overclocked by 85 MHz / 200 MHz over the NVIDIA reference 8600 GT design, we could get another extra 140 MHz / 115 MHz out of it - without any change to the cooler. So compared to the regular 8600 GT we could reach clocks that were 42% and 45% higher than NVIDIA's reference design.
Our benchmarks show that the GeForce 8600 GT Turbo from VVIKOO has a nice performance advantage over the 8600 GT out of the box, but it can not beat the 8600 GTS. Once we overclocked the card, this was not a problem anymore. Especially at higher resolutions there is quite a difference in performance, big enough to be noticed while gaming.
The price of the 8600 GT Turbo is only $20 more than a regular 8600 GT, so if you are in the market for such a card, spend a few bucks extra and get a nice performance boost.
