But you'll never be faster than the backplane speed - EVER. That's the
limiting factor and currently only PCI-X 16 (I think that's the big one)
offers Gigabit performance. There's nothing out there that fast.
The biggest factor in performance is HOW YOU USE THE COMPUTER. It doesn't
matter how fast your HD is, how much RAM you have, how many bits your CPU
is, if all you do is surf or type docs then who the hell cares? I know this
very well as I design, maintain, and help run a rather large
high-performance data center. The end-user and the application determines
performance more than anything inside that box/es.
That's why I'm rather blase about gigabit network to the web - all it means
is more junky web pages and more spam and pop-ups per session for me. I
sure won't be typing at gigabit speed.
