Telling a 9 year old (I believe he said he was) all this would probably sound gibberish to him, since he may not know what the hell we are talking about.
Closest to what he would under stand is "SUPER-HYPER CRYSIS PC 4000", which translates to an overpriced computer (which can be built for cheap).
Note, this isn't to the original poster:
Yeah, it seems a lot of people who try to ask advice on what microphone, computer, or video recording software to use, always seems to be too young to understand any of it anyway.
I think if you can't grasp the general idea of something, you should either study it really hard yourself until you become a master at your craft, or wait a few years.
If you're 17 and you have a job, hey go out and get you a nice computer. Learn to build one. It's awesome.
But if you're 11 and you're begging your parents to build you a custom computer and you literally have
no knowledge of what goes into it (or expect people on the internet to basically DO it for you),
It's going to end badly.
