What's the best beta? IE 8 vs Opera 9.5 vs Safari vs Firefox 3

one of FF 3's key improvements is its better management of PC resources, something that should've been fixed in a previous version.

We do like the lower memory and CPU overheads though -- IE 8 was less resource-intensive than Firefox in our tests, so new computer users or those with less capable machines may be perfect candidates for IE 8. 

It's clean, it's fast and it just works.

Along with linked bookmarks, the terrific page indexing and searching, and general ease-of-use makes Opera ideal for students, or indeed any researcher, who needs to quickly plagiarise look up a quote, reference or source.
