oh wow. those acards do help at game loading times. when is the last time you have seen a single ssd load that fast? i think whay you mean to say is that they dont scale well. it is also if the games, programs etc take advantage of all of the processor core ( multithreading, multicore usage)
throw in my usual comment about not just game loading times being pertinent information, performance being key as well... etc etc yada yada yada
