I recently purchased Omnisphere, and, after playing around with some of the stacked presets, I've come to realize that my 2.4ghz Core2Duo isn't quite up to the task. So I've decided to upgrade my system. My question is, which would be better able to handle Omnisphere: A Core i7-920 (2.66ghz quad core), or a Core2Duo e8400 (3.0ghz dual core)? I'm also willing to consider a Core i7-950 if necessary. Thanks.
