Spec needed

[Phill4321]

Basicly my budget is £450, heres the spec I have come up with so far.

All I need is a new processor, ram, HSF to overclock, gfx card, motherboard + power supply. Intend to recycle some old parts, os, HD, case, etc

My current spec is 3ghz pentium4 sckt 478
250 gb sata hd that ill use in new build
a rubbish asrock MB that supports my 478 socket P4 an has pci express
1gb ddr 400
radeon x1800xt

Basicly my question is will this new build be a lot better than what I have. I also intend to get this cheap processor and overclock it to 3GHz then replace it with a quad core when they are cheaper, hence the good motherboard. Also will the x1950xt be better than my x1800xt?? need a new gfx card as the old one will be given to my brother along with my other parts, so is what i have chosen any good for the budget or is there anything I can improve?

Thanks for your help

Cos then ill go over my budget of £450 and also I intend to wait until the new DX10 games come out and then ill get a new card based on which ones perform best in Crysis and so on. Not rly in any rush for DX10 yet.

you could drop the ram to Ballistix PC5300 and the motherboard to a P5N-E or Gigabyte S3. Use the money saved to try and sqeeze in an 8800GTS

Are these motherboards really future proof, for quad core and ddr3??

I could maybe scrounge some money and stretch to £500 allowing me to get the 8800gts, is it worth the extra £50?? and how is its performance compared to the x1950xt??
