Vvikoo 8600GT Turbo Review
Vvikoo is a relatively young company by GPU manufacturer standards. Founded in February this year you might think it's coming a little late to the game. However, it has some converted heavy hitters from aBit behind it and an extensive list of investors. The first GPU they have sent for us to take a look at is their 8600GT Turbo.
