Did you buy an entire Alienware or just the case to one?
Do you have a link to your wallpapers?
Yeah you can upgrade that machine, it should be able to take 64gb ram, but I've only seen people go as high as 32. (Mine has 16), in THEORY you should be able to stick an ivy bridge E processor in there, but I'm not sure if the latest BIOS update supports it. They're nice machines! Keep an eye on your CPU temps though, the water cooler's CPU block has been known to get clogged after a year or so. Your best bet would probably be more ram (faster ram?) and a new video card, if you ever need it. :)
Gtx 555? am i reading that right?
I was going to downvote because of the alienware but then i realized we're all part of the masterrace, big or small, nice setup :D
