For the record, here is a screenshot of my Opera browser, displaying 99 open tabs and using only 2.4GB of memory, with zero performance issues. What can I say? I'm really ADD. 
That's a lot of RAM for 99 TABS, I got Firefox running with 55 TABS, all of them accessing Web pages, not empty, and I'm only using 524MB of RAM.
Staying on topic:
That's great performance out of the Vampire, finally someone showed Doom running on Vampire!
