I bought a customized Aviator G something from Hypersonic-pc.com . After I bought it I started researching on the internet. (Real smart to do it AFTER buying one right??) What I am wondering is, I got a P4 3.0Ghz processor and 1024MB PC3200 DDRAM ( I think, check out my rig, I know it is right on there) in one slot. Was I stupid for not getting a 64bit Athlon and 2x 512MB DDR Dual Channel?? I will be using this primarily for gaming and would have got a desktop but I move A LOT being in the military and all. I got the 1x 1024MB because I figured I could get another when I had 500 or so dollars laying around again and then have 2GB of RAM, which I had not dreamed of till I saw it on the site. I have been very out of the loop for the last few years, and am just now learning how much I DON'T know about computers, so any help is appreciated. Please, if you post a reply, imagine you are speaking to a 4 year old, so I can be sure to understand it. And one last thing, since I have already had this shipped to me, what recommendations would anyone make for upgrades? Thaks to all, sorry for my ignorance.
