PC Stats put up an AMD Sempron 3600+ 2.0GHz Socket AM2 Processor review. Here's a taster:

With a retail price of $117 CDN ($105 US, £55GBP), the AMD Sempron 3600+ is an absolute steal. From the benchmark results in workstation style applications the 2.0GHz Sempron 3600+ is competitive with the competition, often equaling Intel Pentium D performance. In these office oriented applications and it is not even that far behind AMD's higher end processors.

In tests that require a lot of CPU power, like games or rendering programs, the AMD Sempron 3600+ lags behind mainly due to a small L2 cache size. AMD had to handicap the Sempron a bit otherwise it would steal sales away from the socket AM2 Athlon64, much like how the socket A Duron stole sales away from the AthlonXP processor.

In 3D applications, the smaller L2 cache size holds the Sempron 3600+ back a bit, although it is not as much apparent as with pure CPU-number-crunching tests. Team the AMD Sempron 3600+ up with a high powered videocard and a fast motherboard and you should have a pretty decent gaming machine, as the benchmarks indicated. You'll get much better framerates from an Athlon64 X2, but the two are wildly disparate when it comes to cost....

The 2.0GHz AMD Sempron 3600+ processor offers users on a budget a stable and reliable platform from which to build a workstation PC. The Sempron 3600+ is the ideal chip for mundane tasks like word processing, spreadsheets, email, surfing the internet and like chores - particularly if total computer cost is a limiting factor. If you decide you want to have some fun the Sempron 3600+ is also up to the gaming task so long as you've splurged on a good videocard, but just keep in mind that it won't break any FPs records when you're blasting away at enemies.
