2 X 512 or 1 X 1024

Alright bit of a noob question here with not a lot of experiance with building computers, compared to a lot of yous ( have stripped down and replaced some componants but replaced them with the same parts or better with regard hd ) is there any difference between using lets say using 2 512mb cards rather than using a 1gb card ?

like i say the only time ive really upgraded ram was on a p2 233Mhz upped from 32mb to 64mb.

still trying to gather info

Yes, if you have a dual channel chipset and processor.

so say i went for a single core proccessor it wouldnt make much of a difference ?
just looking at the wife old pc which i was looking at stripping down for parts its an old AMD 650 and it seems to have 3 ram slots. only looking at the HD (which was replaced to a 120 GB one) Dvd/cdrw and the power supply. until i get it all setup ready for the car where ill look at a proper car one wired in. Motherboards buggered anyway so itll save me some money.
and on my main desktop, 2.4 pent 4 even older than the wifes, theres 2 slots both have got 256mb in them and it shows as 512mb.

sorry also meant to ask what the difference is ?
is it a case of 1 core would use 1 and the other use the other ?

no no,
what he meant was your motherboard that supports dual channel. Dual channel motherboards allows better performance using 2 chips (ie 2x512mb) rather than 1 (1x1gb), at the same memory amount. It'll say on your motherboard's spec whether its dual channel or not. Nothing to do with single core or dual core processor.
