For all ye know it alls here a bit of info for u,

Amd started out by infringing copyright and ripping off intel

If u buy Amd u better pray and hope ur heatsink/cooling system doesnt fail cause ****bang**** any1 for fried chip, intel will shut off.

Dell dont use second grade stuff ive had every make of pc and the only 1 not to give trouble is a dell(sony, sharp, samsung, lg, intel, ati, nvida, western digtal, kingston) all the crap parts there all right.
4.) if u build ur own and parts fail it will take u weeks/months to get the prob sorted out dell 24-72 hours(depending on warranty).

Alienware are the biggest rip off pimp my pc lol kinda sad really stickers on ur pc 3k well worth it.
6

Reason dell use nothing but intel is cause they own shares in each other
