I have a quad-core, 8GB machine at work and a dual-core 4GB machine at home. Both are running Win7 64-bit. How much more do I need?
I have noticed slowdown in Firefox's UI on both machines. More important than number of tabs, is CPU usage. For example my HTML5 heavy trading platform often causes the single-threaded Firefox UI to freeze and slowdown on both machines, while I have never noticed Chrome freezing when this site is open.
On the other hand, Chrome's UI runs smooth as butter until either open tabs or other programs bring memory usage to over 90% Physical Memory in the task manger. Recent builds hit that wall a lot quicker than it did a year or so ago.
