From this part:
1,800 MHz = 3,600 MT/s = 7,200 MB/s
2,000 MHz = 4,000 MT/s = 8,000 MB/s
2,400 MHz = 4,800 MT/s = 9,600 MB/s
2,600 MHz = 5,200 MT/s = 10,400 MB/s
Socket AM2+ and AM3 processors and their companion chipsets, however, are limited to the 8,000 MB/s transfer rate. Only socket AM3+ CPUs and chipsets are capable of using all the speeds published above.
Does this mean that since the CPU I'm using is an AM3 socket, it doesn't matter if I get a 4000 MT/s, 4800 MT/s, or 5200 MT/s mother board?
Also, if I don't plan on upgrading my system with the future, is it okay to just get AM3 motherboard for my AM3 processor?
