You should buy Dell Alinware its cost around 2000$ to 5000$
Id say $1000 would buy you a really good computer
It's all about your budget and what your going to do with it.
Lets say your not too big of a gamer you can pick up average parts for a decent amount of money like around $700 or so. If your a huge gamer you can go hardcore with a setup of like $2,000 consisting of only the top of the top Graphics Cards and CPU's. Keep in mind you never want to overdo what your working with. If you end up buying a $3,000 build in which you can't even use 10% of the power on your not going to feel good. I currently have an extremely decent build (Intel i7, 8 GB of RAM, and a GTX 570) and won't be using any of it's power anytime soon.
Too much is 2k. $600-$1500 is the range I think for performance.
$600 to $1300 for a new PC is ok.
Game PC will cost u more in my opinion.
Let me know if u buy an PC and the price
My gaming computer is cost 3.5k$ to build while my traveling computer cost 600$, then my file server for my store cost 46k$.
