FX-55 > no overclocking?
You will probably change your mind about that sooner or later...so get some good quality pc3200 memory with LOW timings...u can still overclock that memory pretty nicely, and i doubt you will be pushing that system to its limits, considering u have no intention of overclcocking right now....
So, since u dont seem to be poor, or maybe u thought something like : "enough with this slow computer, im gonna buy me the fastest sh*t out there!"
>>> I would certainly NOT go "budget" on your memory all of a sudden...
p.s : forget DDR2 memory, its of no use to your system, in fact it will slow you down (terrible timings)
