Want a new Gaming Desktop, need direction

With Battlefield 3 coming out and looking ridiculous, I think I'll be needing a new desktop. My roomate built my current one, but with me at the wrong end of the country now, I'm looking for some advice on where/what to buy.  I'm not looking to build a PC, I really don't have the knowledge to  do it myself or the time to figure it out, so does anyone know of a good brand to look for or PC community to turn to?

I'm in the same situation. I may try upgrading my current rig, but all I know how to do is put in new ram... lol

If you are in North America,  check out ncix.com. You can choose one of their pre-mades or build your own.  You choose the parts, and they'll put it together for you for $50.
