Quote: In game benchmarks we saw a ~38% performance gain by running a 2133MHz memory kit versus a 1333Mhz memory kit. This is a major performance gain a nd obviously shows that the AMD Radeon HD 7660D integrated graphics was bei ng bottlenecked by the systems memory. If you ever plan on playing games wi th an APU powered system then youll want to go with the memory kit with th e highest possible clock speed that you can afford…
