I just made Oracle (DES-based) passwords cracker for x86 utilizing SSE2 instruction set. On my (relatively modest today) Intel Core 2 Duo E6600 (2.40 GHz) I got nearly 6M password/hashes per second. On Quad-core Intel Xeon X3430 (2.4 GHz) I got 16M password/hashes per second. The most powerful computer I had access to is Dual Six-Core AMD Opteron(tm) Processor 2427 (2.2 GHz) and I got there 36.5M password/hashes per second.
Win32 and Linux versions can be downloaded here, plus source code as well.

I also made public all source code of FPGA-based Oracle passwords cracker:
By the way, it is still connected and running (I hadn't any reason to turn it off yet) for more than 6 months:
