Ram I know there are some good RAM gurus out there. I've decided to upgrade my RAM so I can play WoW after graduation. Yeah, I got sucked in, should be fun though. Anyway, apparently I have expensive RAM, it's PC800. I have 512 and want to bump up to 768 or maybe 1024. Toader has already helped me out a bit and it seems ebay is my best option. But I want to know for sure from some of the smart people here, is PC800 the only kind of RAM I can buy? It's hella expensive. And if I'm buying RAM from ebay, is there anything I should look out for?
