It will probably help, maybe quite a bit. Most of Vegas' speed is related to the processor. However, the speed of your motherboard's buss and memory and the hard drive speed will also affect it to some degree and changing the processor won't change those speeds.
I have a dual Athlon MP1800 setup. For arguments sake, would one XP2000 give better external previews than Dual 1800's? Does the amount of memory matter?
"If I through a 2.8 in my 1.8 box will I get better external preview via firewire or is it unrelated " - "It will probably help, maybe quite a bit. Most of Vegas' speed is related to the processor.

Also note that it's not always possible to upgrade just the CPU - in fact found it rarely pays in the few cases where it was possible. Need to check the manufacturers site etc. and see first if the desired cpu is supported.
you may be looking at replacing both th emotherboard and processor.
Actually that would be a wise investment as you may gain even greater results. Most motherboard more than 2 years old do not support ATA 133 (the newest hard drives) speed. So if you have an ATA 133 you arent realizing its full speed unless your mother board supports it usually a good mother board can be had for under 200
Whose got a drive that can sustain (for video) 133MB/sec, or even a pair of 66MB/sec drives that have no spikes sharing the same cable?
I see that the quality of the preview depends on the complexity of the timeline.
I'd like to see a standard .VEG file and contents being benchmarked for realtime DV functionality without pre-render. Maybe 3 layers with 2 filters and a mix of so many scaled and so many generic D1 size JPG of a certain compression size, and maybe a 5.1 audio track setup with keyframed position tracking.
Memory/chipset bandwidth, non-contention in the I/O susbsystem and current IDE or SCSI (SCSI having less CPU usage per transaction) storage, in addition to CPU speed is important. "Realtime" means different things to different users and vendors as does "preview". Certain things need high resolution, smooth "preview", most of my work doesn't so I can pre-render. I'd expect that some people would feel held back by this and want custom-chip DV editing performance from the CPU alone. It is almost difficult to tell the difference and it is certainly cheaper to upgrade a software-only editing system (be it DV,uncompressed, MJPEG etc).
What CPU speed would someone suggest to satisfy 95% of timeline events for top resolution, fully activated plug-in chains to appear on preview, be it on VGA monitor or DV-out?
