The Overclockers league is based on a members best 15 global & worldrecord submissions, and the best 20 submissions with the most 'hardware' and 'competition' points. Global or world record points can be achieved by reaching a very high score in a benchmark, no matter which hardware you used. Hardware points can be achieved by reaching a very high score in a benchmark for a specific hardware item, like the fastest GTX260 in 3DMark06. Competition points can be gained by joining competitions.
