I would never go with that brand. Because with that brand, you get so much gunk on it, you need to reformatt as soon as you get it. Plus the parts kinda suck.
Go to one of the sites online, that you choose the parts, and they make it for you.
What I do if I ever buy a prebuilt is I always get it home and format and install a fresh OS and driver set. That way all the preload software junk is gone and it will run better. As far as the computer, I concur. Up the RAM and the video card, and if you really feel like splurging, up the HD.
