It took a 1min and 30sec on my PC. WinXP, P4 1M Seconday Cache (Prescott), 1G RAM, Rendering to a 7200rpm non OS serial ATA drive. The resultant file is a 18,704KB avi.
Now, all the video settings said that it would render out a 720x480 file, but when I view the final result with Windows Media player it apears to be half this resolution, so I'm not to sure what's going on. I've really just started digging into video in the last three weeks. I've been using Vegas for three years, but primarly for audio.
I have a 2.8 Pentium 4 with HT and its FSB with just ho-hum 3200 memory is at 960. That pushes the CPU clock to 3.360 GHz or a 20% increase in performance for 30 seconds work.
If you or anyone else is game, research your motherboard on the web, or read the fine print in the manual. Easier to look for sites that review motherboards, then see how far someone has pushed it. With some motherboards all that's necessary to get a big boost in performance is changing a switch or two from your BIOS (setup), which is all I did for my ASUS P4P 800 Deluxe. You don't even have to open the computer case. Just tweak the build-in set-up on a re-boot or cold start up.

It'ss set correctly. What BillyBoy is suggested is that you can overclock your Prescott processor. Some people don't like overclocking because of the FUD factor- they think you'll increase the chance of making your system unstable and/or killing your processor. IMO the is very, very little risk if you know what you're doing. I must admit however that my computer used to reboot randomly (about every other day) but test fine when overclocked using stock cooling. Changing the thermal pad to Artic Silver 5 seems to have stopped that problem.
Some motherboards don't support overclocking. Whatever your motherboard is, I suggest checking the forums over at abxzone since they typically have very useful info on your motherboard in regards to overclocking.
When you overclock the processor will generate more heat, which makes the processor unstable if it's too hot. Heat is the main limiting factor. Replacing the thermal pad that comes normally with thermal grease like Artic Silver 5 is not very expensive but will help. The Artic Silver website has information on how to remove the thermal pad. It's better if you didn't let the pad melt in in the first place but I didn't do that. I scraped mine off with a plastic knife and had to scrub a while with Q-tips + rubbing alcohol to get some of the rest off.
Once you overclocked your system (depends on your motherboard) the most important part is testing for stability. The best I find is running CPU Burn and prime95 at the same time.
2- The Prescott is a really hot processor and not that great for overclocking (see http://www.hardocp.com/article.html?art=NTg5). Actually I'm not so sure if it's a good idea, but I think overclocking that processor is fine when you don't go extreme with it. You should be able to get maybe 15% better performance out of it. It should be noticeable in Vegas (you'll see the bar move faster) but nothing really major.
