Do not get alienware, they are overpriced, as I said before, get a Cybertron Fortress, they are cheap, well made, and massively powerful.

pkmn the link you attached seems pretty good for value of money. it is pretty much the same price as a mac. The spec of the desktop are pretty good. That brand of cpu also so a lot of tips on how to upgrade the hardeware very eaisly. Alienware was good until Dell brought out the company. dell have reduced the spec in almost all alienwares products and charged more as i said go with the link you had if u want a good affordable gaming cpu. Also most mac have limited gaming compatibility, many dont even have a dvd-rom.

Aside from the case being absolutely butt-ugly, the linked pc looks OK.

You could put 2k into a custom rig and get twice, if not three times, the rig. Takes all of 15 mins to throw together, and maybe a few hours installing windows, drivers, and updates...
