Testing notes
We're testing the PURE Platinum in two ways. First off, it's a straight comparison against two other FM1 motherboards and an Intel Core i3-2100 chip on a Z68 motherboard.
Secondly, taking into account the enthusiast-level features on the board, we have run the A8-3850 APU at a roughly-matching frequency but with a 133MHz clock - 2,926MHz, 133MHz clock, 22x multiplier, DDR3-1,773. Doing so ramps up the graphics speed.
