Several analoge synths, Fm synths, samplers, FX's to this kind of money are amazing. Ok, it's a CPU hog, but when I load the Minimoog, or the Juno106, the CPU load imidiatly shows. 20 % with manymoods 6 voices, and thats it, (p3 850mHz). No surprises in CPU load after loading an ensemble. My favorite is the Drumatik, a analoge drumsynth, with 8 voices. What about a Simmons set in your PC...no problem with the Dynamo. Nanowave, incredible PPG emulation. If you need a synthcollection, this is it.
