You seem desperate
I Buy Power, Seem's like a great webpage and is very popular. They have overall good customer review's but some seriously bad ones. I alway's suggest to a person to build there own computer, and if you arnt the age to do what you want, then you might want to show anafe responsibility and respect for your parent / gaurdian to let you do that, Show them that they can trust you anafe and that your responsible anafe to do something that can be a good expeirence or can be a dangerous expeirence if you do things in the wrong way. But, If you dont know how to build your own, I'd say I Buy Power is the way to go.
EDIT: Did A Little More Research On IBP. They are a Major Rip Off. More then Tiger Direct, I did a 2,500$ AMD X4 Computer Build on the webpage, that I could build for a 1000$ Cheaper.
Hope This Helps,
