Alright, I'd like to upgrade my computer, I want to have a 64 bit processor, the thing i'm wondering is, do all 64 bit processors have the same performance, or is any of them faster than the other, because the prices on them range alot, and i'm wondering how others are better than the other one.

Anothing thing is RAM, I currently have 512MB's of ram, I'd like to get another 512 so i have one Gig(i think), I already see one that I'm interested in, costs 100$ and, like, can i just through in any kinda ram in my computer, i have an asus motherboard.  Does it have to be a specific kind, like does it have to match the brand or does it have to be teh same.  I don't usually mess with computer hardware.

thanks
