really how often are you reading files much larger than 128kb? that card is a screamer man, ultra low latency and snappy as hell. i love it ! it is fast as heck, and very low overhead. in real world testing against the 9260 that i did (pre-fastpath) it was right there with the 9260 on game loads, etc. there is a point of diminishing returns of course. much over what you already have there isnt going to yield huge returns. ...unless you are doing tons of writing id stick with it, the cache on the 9260 is good for writing, of course.
