OT: Athlon64 performance questions

I currently have Athlon XP 2800+ (32-bit). It runs at 2080MHz, has 512kB L2 cache, and supports MMX and SSE (not SSE2 and SSE3).
Recently, I have realized that I need something faster. I was encoding 7min 38sec one video track with effects like brightness, contrast, saturation, curves and unsharp mask turned on. It took about 3 hours. My friend then allowed me to use his Dell server with two Xeons 3.6GHz, 1MB L2 cache, MMX, SSE, SSE2, SSE3. I was blown away! Once the estimates timer started running at normal speed, it was showing about 35 minutes render/encoding time!
3 years ago, I switched to AMD because it did renders in Vegas faster. Now that I need to upgrade, I am wondering which one to get.
I am also wondering if 64-bit Athlon64 CPU will do stuff significantly faster than the 32-bit CPU running at the same clock speed, and having the same L2 cache size (512kB).
How much will added SSE2 and SSE3 benefit my speeds, and how much more will I get from a 1MB L2 compared to 512kB L2 version of the same clock speed (like 3500+ compared to 3700+).
Has anyone ran some real-wprld tests in Vegas with these CPUs?
I would hate to have to go and get 4 different CPUs, and 2 or 4 different motherboards, just to keep one in the end. Fry's already has me on their red list :-D
There are ways around it, but I would rather not.
I would really appreciate some serious input on this!

i belive that only the very fastest intel's beat out the AMD's, but the AMD are WAY cheaper at that point.

No CPUs from intel (not even their $3,600 Xeons) get very close to the AMD Opterons, search for previous threads here and at the hw geek sites.

Medium AMD X2s are currently optimum for bang/buck ratio, although Pentium Ds are certainly acceptable.

The problem is that your AMD chip is old.

Intel is suffering from architecture problems right now. Do yourself a favor and avoid Intel CPU's for the near future. Read these benchmarks and you will soon agree: http://www.gamepc.com/labs/view_content.asp?id=paxville&page=8
