So I just finished my first ever watercooled system
Its a 2500K with 2x6990. Watercooling consists of two alphacool blocks for the graphics cards and xspc raystorm block for the cpu. 18w DDC with xspc res top and 560 rad. running nice and cool and near enough silent at about 50C. Its currently the highest rac host on Milkyway
What res do you play at?
2x 6990 is an overkill for most people
