Benchmarking The EX475 With Sempron 3400+, LE-1640, And BE-2350
Interestingly, the LE-1640 and BE-2350 bring different strengths to the contest so that the outcome is not as cut and dried as you might expect. Table 4 includes the values from the NASPT benchmarks for these three processors, where all were equipped with 2 GB of RAM.

I went into this exercise expecting the dual-core BE-2350 to swamp both of the other single-core processors, but came away believing there’s no clear advantage here. Except for inveterate tinkerers, this tells me that a CPU upgrade isn’t really necessary. In fact, if you accept the sum of all benchmark values for each processor as a rough-and-ready basis for comparison, the 3400+ comes out on top (596), followed by the LE-1640 (588.9), trailed by the BE-2350 (576.7).
Of course, there’s only a 1.2% difference between the 3400+ and the LE-1640, and 2.1% between the LE-1640 and the BE-2350, so we’re talking about a total variation of 3.3%, which I have to believe is completely within the range of sampling error. With no clear advantage for upgrading, this becomes a completely discretionary task.
