HEYA! Long time no see, hopefully SOMEONE remembers me.

I just ordered a refurb'd Gigabyte SINXP MB from Newegg.com yesterday, and as per usual, despite the time I ordered it they shipped it out withing 2 hours. Damn I love'em!

Anyways, next month I will be getting my student loans in, and I am attending Full Sail for a Digital Media degree and I need some upgrades to my current system. I figure a new Motherboard and some RAM will do fine.

It's also been about 9 months since I last had the ability and money to spend on Overclocking so I kinda miss it. Before I go on my system specs ATM:

Gigabyte P4 Titan 8SG667 MB(this is Rev.1 so no Voltage or even Temp monitoring! Unlike the reviews showed grr)

P4 2.4B @ 151MHzx18=2,718MHz

Corsair XMS PC3500 C2 512MB (1 stick running only 402MHz, won't go higher on this board.)

ABIT Siluro Ti4600 (originally bought a Ti4400, but newegg came through and asked if I wanted the Ti4600 instead for the cheaper price of the Ti4400) runs @ 320/675.

So, I need to know what memory you guys suggest for my Dual Channel capable board coming in.

*EDIT* Just realized my sig shows off my system stats, but my CPU isn't overvolted anymore, it's at default)
