That's a great build and I'm sure your dad will be pleased for a long time.
|But...I don't know which what type of car do you drive and which school you ended attended, how big your house is, but if you have i7 and crossfire cards you aren't rich.
I'm a teen and i could bought the same rig as you did if I wanted(needed) it.I will probably buy new gfx but not because i need it, just because few friends has 4870 or 4870 and my "need" wish more.
Your statement isn't entirely true. Some people could afford it, yes, but you need a certain amount of income to be able to afford a pc like that (aka not necessarily rich but have a modest income). The other issue is priorities. I too could probably probably afford a pc like that, but I'm putting away for college because I'm shooting for med school eventually.
