Best place to get a PC?

Where is the best place to get a Pre-Built PC? I was thinking Alienware x51 the $800 one.

Here's the specs for the Alienware i was looking at.

Intel Core i5-3330 

Windows 7 Home Premium 64-Bit

8GB RAM @ 1600Mhz

Nvidia GeForce GT 640 1GB GDDR5

1TB HDD 7200RPM

That's the specs. I was thinking some were to get one for about $700 at the most $800.

If you must buy a PC, for god's sake don't buy that. Why not just build your own? PC's are completley modular, building one is like putting together legos.

I don't have the time to build one or i would.

It takes, at most, a few hours to build everything and have Windows/Linux installed, with all of your drivers. It is much cheaper to build your own, giving you equivalent power for less money, and much more power for the same amount of money. I would highly advise building your own.

If your not going to build one, which I highly recommend, I would recommend buying a pc from cyberpowerpc or ibuypower. They seem to be a little bit more reasonable. You could get this http://www.cyberpowerpc.com/system/CyberPower_Z77_Configurator/ but change the 650 to a 7770.
