Firefox may crunch memory, but Vista's worse.  Firefox + XP > anything + Vista.

Opera can get all the features of firefox...

No where near.  Opera ain't open source, so it'll never attain the status of Firefox.
Plugins like FoxyProxy and Firebug simply don't exist, and probably never will, on Opera.

It runs slow on 1gb of ram, but 2gb or more is perfect for fast pace prefromance.

No as hard as Firefox.  About 100MB of that can be accounted by Vista's crappy Windows Search (which makes the HDD go crazy without you doing anything, meaning your HDD dies sooner).
Vista has never performed faster than XP, even with 4GB RAM.  Absolutely no benchmark or test whatsoever has even demonstrated such a thing.  XP actually did have a speed gain over Windows 98.

Having said that, my nLite'd XP x64 pwns Vista any day.  nLite XP 64 takes about 120MB on installation.  Normal Vista install is 400MB.  Calculate for yourself.
