Yet another what memory to get thread...

Well, it is time to upgrade again. It was suggested to me that more memory would probably be the best bang for the buck at this time. Original post is http://www.ocforums.com/showthread.php?t=475311 .

Anyway, I'm trying to figure out which memory to get. Going through newegg and the options seem to be:

http://www.newegg.com/Product/Product.asp?Item=N82E16820231020 mainly for the budget, though G.Skill has a good rep.

http://www.newegg.com/Product/Product.asp?Item=N82E16820231032 G.Skill again, but with better timings.

http://www.newegg.com/Product/Product.asp?Item=N82E16820145596 Both about the same price, and both DDR500, which searching here looks like it might be better chips to work with the DFI Lanparty motherboard I have.

http://www.newegg.com/Product/Product.asp?Item=N82E16820227210 OCZ, and essentially the 2GB version of what I already have.

Oh yeah...

It is also my birthday, so I was hoping to make a decision today.

If you haven't decided already, outta all those choices, my vote goes to...
http://www.newegg.com/Product/Product.asp?Item=N82E16820145596

Or the 2GB version of what you already have is good also.
