Pros: Works great in my picky Dell e510. Casual gaming and audio/video editing are much smoother now. A noticeable performance gain from 1 Gig, but only while using certain applications.

Cons: None.

Overall Review: I would have thought I'd notice a much greater performance gain in day-to-day tasks when upgrading from 1 Gig to 3 Gigs. This upgrade didn't have the same "bang" I got when I went from 8 Mb to 40Mb in the early 90's ago, but when I need my applications to work, boy do they work!
