TADA!
As you have a gig in there already (and it's a pretty awesome speed) I would either get the 2x 512Meg sticks to get yourself up to 2Gb (though, actually, it looks cheaper to buy 2 single 512Meg sticks as it's non error checking, which you don't
really need for a desktop...). However, if you want to up it to 3Gb (by keeping your two 512Meg sticks), get the 2x 1Gb sticks - but make sure you put the 1Gb sticks in slots 1 & 2, and the 512Meg sticks in 3 & 4 dual to the lovely dual channelness of
your mobo.
The data sheet also says your mobo takes non error checking (NON-ECC) RAM, which pretty muchs means it won't be used if you buy error checking (ECC) stuff - so it's just a waste of money really, but won't mean it won't work if you do buy ECC.
ENJOY!
PS - shop around for cheaper stuff if you want. You want PC3200, NON-ECC (preferred) memory, and your mobo can hold up to 4Gb (so buying two 1Gb sticks would be best for you at this point without throwing out your RAM you have at the moment). BUT REMEMBER! You have a dual channel mobo, so slots 1 + 3 need to be the same as 2 + 4 respectively to get the best performance out of the memory!

Edit - don't want to make a new post for this, but whoever moderated me, thanks! I would give you some rep, but your name is unknown to me! Thanks though!
