Hello, and welcome,,
1) well honestly i can say that i have never used an amd, but i will say that both companies are very good, but at the moment, intel has the faster cpus, while amd has the best bang for the buck, but if you are ever considering overclocking on this computer, even a way into the future, then intel (core 2 duo) is the way to go, they OC like mad. but in the way of value, amd is leading in the cheap end, but not by much at all. and the new e4000s from intel are very good, i have one, as for the L2 cache, definately over 512kb like eagle said, but i dont think it makes that much difference, when i OC my 4400 to 6700 levels, even though mine has half as much cache it still goes just as fast, at this point in time the cache will affect very few things at all, infact the only thing with a noticable drop due to cache is super pi, but i doubt that you will for some reason need to get 32million digits of pi asap any time soon
2)In this section i can say the last 3 are good companies, i dont know about gateway, they dont operate over here in oz. but if you want this pc for gaming or anything that will require 3d power, then order by your own specs, they generally come with generic integrated video, some of the more expensive ones come with dedicated video, but from my experiences with friends PCs, up until the midrange they dont
3)I cant vouch for it personally, as i live in Oz and all, but from everything i read on the internet it seems that
Newegg is a well known site of most american pc enthusiasts. also if you want a custon order pc, why dont you try looking at some local pc shops, its places like these that i get all my stuff from, good luck with youre new system, be sure to let us know of youre final decision
