Alternatives To Korg Legacy? Options

[mechcon]

Hiya, I'm new to vst's, and what not, and I recently got into ableton live 6.0.1. I got a powerbook g4 1.67GHz w/ 2gb ram w/ os1 10.4.8

Problem I find is that i like the sounds like ultimate trance, and trance leads, amongst others! and I use the other ones too, that come with the Korg Legacy vst Legacy Cell. Problem I'm facing is that its very cpu intensive once I throw 3 of them into the session! (only alternative, and a good one to boot is the freezing of tracks)

I was curious to see if there are any other vst's out there (even free ) which produce trance leads as such?

I guess im glad i bought korg legacy 2nd hand then


Thanks guys would love some input on this scenario
