This is kinda a continuation of my previous question. I am trying tojustify spending $219 on a Seagate Cheetah 15k.3 36gb and another $150 on a controller.

By the way, what is the difference between

LSI U320 Single Channel PCI-X SCSI
LSI Logic Single Channel U320 SCSI HBA

Other than about 45 bucks, I can't find out what the differences are.

Back to my issue. I am running some diagnostics on my machine to see if I should upgrade my CPU/motherboard etc. When I look in my task manager (winxp) it says I am using 100% of my CPU and 247MB of PF. I used another program I downloaded and it shows my CPU hitting 100% about every second. But most of the time it seems to be at 0%. It just kinda blinks up to 100 for a split microsecond and then back down for a half second pause, then back up. etc etc. Same with my RAM. It also shows SWAP. I am not sure what this is but it is at a steady 28%.

My proc is an AMD, and I think its a 2100 or 2200. Something close. I bought it in march of 2002. Its around 2GHz if I remember correctly. Also have 1gb of ram, can upgrade 512 more.

Intels new chipset looks awesome. Maybe I'll wait till its been out a yearand try to find one on sale.

I think I explained myself wrong. I am not trying to justify the money, but the need. I was wondering if there were other upgrades I should make that would be more important or better for performance other than the scsi drive. I am using a diag program and my cpu isn't spiking anymore, but my ram is only at 350-400mb, and I know i have a gig in here. What are SWAP? and VRAM? at 13$ and 5% repspectively. Anyway to get better use out of the RAM?

It seems there are so many things I could upgrade I just want to do what will have the biggest impact. Or, possibly just upgrade the entire machine.  Considereing my motherboard is an ASUS a7v333-x, rather old and on the cheaper side.

Performance is only dissapointing when I try to do things like edit video. Normal photo editing is usually o.k. Unless its huge or I am batch editing several 8mb imiges at once. I do a fair amount of batch editing. Can take 5 to 10 minutes if I have a very large batch. Compressing video on DVD is very time consuming. 2 hours worth of film being compressed to fit on one single layer 4.7g dvd takes about 3 hours or more.

The SCSI guide really made it sound like that would help the system alot. But I don't know that much about computers so I wanted to make sure. I chose the Cheetah because when I upgrade the rest of my stuff (who knows when that will be) I will move the cheetah over too.

Editing is Windows Movie Maker or Nero 6 ultra. I compress them using DVD Shrink and burn with Nero 6.
