From a financial standpoint, I think sticking with the AMD/9800Pro would be best if you have those options because the jump from a 9800nonpro to a Pro version is about $100 at retail.
While with the Intel/9800nonpro you get a hella jump in peformance in the video card dept, a true 2.4ghz processor and it has the 800mhz fsb so you get a "good one" IMHO.
A much newer, quieter architechure that puts out less heat, although I can't vouch for the newer P4s, mine is a willamette 1.5ghz.
in your new case, I would have to say go P4 and overclock the 9800nonpro to Pro speeds. I CAN NOT verify that a 9800nonpro will reach pro speeds, some guru around here will have to. Just ask, the nerds know
So theres my recommendation which is based entirely off of what I consider the best deal for the money. That doesnt always mean the fastest or the most advanced but in this case both are true for the "new" intel choice.
In areas I would look at 2nd such as heat production (athlons are space heaters), quietness, and the availability of features such as hyperthreading your got the right pick there also.
Some consider the athlon much faster at FPC (floating point calculations), but I cannot attest to this as my P4 is one of the crap ones and is slower than my 1.46 ghz 1700+ by far in every aspect.
Once intel got into the "C" revision or 800mhz fsb P4s like you are looking at, they got worthy of my very tight, limited, frugal dollars.
And as for the sound, yes the bonus still applies to the AMD camp with the soundstorm as it is fantastic.. but I'd trade it for the P4/9800nonpro.. ONLY if nonpros are near a 100% chance of hitting Pro speeds.
Otherwise stick with AMD the 9800 pro (you dont even have to worry about o/cing the GPU if you get the real deal, and since your gaming your primary concern should be the video) and the soundstorm along with the very respectable Barton 2500+, which can 2.2ghz fine and you'll be wiping the floor with a stock clocked 2.4C.
Like I've said the P4 onboard would sound fine but would only go that route if the nonpro could be guaranteed to hit Pro speeds.
The soundstorm is my favorite sound chip in the entire PC market right now for many reasons.. yes even better than a Audigy 2 IMHO. So if you are investing in an expensive set of cans or speakers then stick AMD you get the 9800pro and a great all around system.
And thats one of the best Athlons for overclockability, dare I say, WICKED.
I wish that intel had nforces!
