Upgrading my P3 to P4

Hello,

I am upgrading my computer from a Pentium 3 to a Pentium 4 on a bit of a tight budget and I'm trying to minimize the number of things that I need to replace in my computer. I don't have very much experience with hardware and I'd appreciate it if anyone could help me work out what needs to be replaced and what I should replace it with... I've included a couple of questions and the specs of my computer below.

Thanks.

Questions:

I'm thinking of getting a 3.0 Ghz P4 CPU.
Is this motherboard (see specs below) compatible with P4 CPUs?
If not, what is a cheap, reliable P4 M\B?
I only have a 250 watt Power Supply. Will this need to be replaced for the new motherboard?
What wattage P/S should I get?

Current Specs:

Motherboard:
D.F.I.
model# CA64-B

CPU:
Pentium 3 930 Mhz

Power Supply:
250 watt

Video Card:
Nvidia Vanta AGP
model#: CE-406

Case:
Wisetek Full Tower

 

you need a new pc

 

you will need a new motherboard, and power supply. while you are at it, graphics also. everything else should be reusable.

if you are looking for cheap, go to newegg and look for some combo deals
