Upgrade for current comp?

[rayman2k2]

I do alot of gaming and video editing and was wondering, for 500 dollars could I modernize the Dell in my sig?

Current Specs:
2.0Ghz Northwood P4
Intel mobo
512MB ram, 2x 256
40GB OS Drive, 160GB Storage Drive
9600XT

My proposed upgrade:
Antec Sonata ~100
Abit IC7-G ~120 (Will get this used as not too many online retailers have them)
1 GB Corsair XMS PC3200 ram ~100
HSF and fans ~80
Prescott 2.4A ~115

Total is about 515. I will be overclocking this, any suggestions for change? Should I get a used 2.4C instead of the 2.4A? Heat isn't a huge concern but I would not like alot of it. Also I do have a DVD Burner, it is not in my sig however.

Also, I have the opportunity to buy a 9800Pro from a friend for 75 dollars. Is it worth it? That purchase would not be included in the 500 dollar upgrade price.

Looks like a good upgrade but you should probably look online at dell systems..you can buy current generation hardware (as in better than what you list) for about the same price with new software included and a warranty.

Then you can sell your left over old system and come out even better.
