That's why I brought up the O300. I bought a 4p 500 a while back (just sitting here now tho), it is surprisingly fast and they are cheap since they are not convenient for a desktop. But put the O300 down in the basement and X-Window thru an O2 ... If I didn't have this monitor that's what I'd do. The flop seems to run just as well on a 4p-500 O300 as it does on a much faster 1p Fuel.
Your points are good in reference to other apps but in the case of the browser, Fireflop is so poorly written that it doesn't make as much difference as you would think. It does run as well on a quad 500 as it does on a much faster singleton. But the design is so poor that slow-loading pages still hang the entire application. Tabs should not be threads, they should be independent processes. And the stoopid thing needs to have a listener thread at the top of the food chain, with priority over everything else. All youse guys with T1 lines think the 'flop is great because you don't have slow connection problems but it ain't great. It's shit. Try for yourself - stick a 10-bit hub between your computer and the main line. Load about five tabs at once. The thing will lock up and ignore you, no matter if it's v2 on Irix or version 11 on Windows. Bad design. Stupid people who could care less about working together to keep the web open, public and accessible to all.*
Anyway, yeah ... between the dual cpu Octane and a faster single cpu Fuel, it would be something of a tossup. That decision depends on the person using it. The Octane really is more impressive looking and better built and more reliable. But for me the quietness, the firewire attachment (it's even faster for me to read an SD card than the Assist can on Windows) and the SATA disk thing makes the Fuel more reasonable for a daily driver. And the dual 600 pimm still ain't cheap. You could get an entire O300 4p computer for less than just that pimm.
But if I were just using it at home to do foolaround stuff, I'd take the Octane. It's a neater computer. And if my goal weren't four V12's to drive this monitor, I'd seriously consider the O2 on the desk with an O300 down the hall, too.
