hahaha, alienwares claims are ridiculous, it says FX 62 is the fastest gaming processor. lol, well i guess currently it is, but if u compare and FX 62 against a single core amd oc'd to its clock speeds the scores would be tight in gaming.
lets see here, here are the specs on the alienware computer:
AMD FX-62
Dual 7900GTX eVGA
XP Pro SP2
700 Watt Alienware PSU
Alienware Board
2x1GB Dual Channel ( no name)
750GB HD
1 CD/DVD+RW
X-Fi Alienware
Logitech X-530
Saitek Eclipse
Logitech G5
Total is $6000
lets see if we can get same performance for cheaper lol. parts from newegg.
FX-62
ASUS M2n-e
G.SKill 2x1GB DDR2 800
2x eVGA 7900GTX
x-fi xtrememusic
3x 250GB Caviar
TT Black Kandalf
Enermax LIberty 620W
NEC 3550A
Logitech X-530
Saitek Eclipse
Logitech G5
and that adds up to $3456, and this is with almost the same parts, now imagine how much more you would save if u bought something less expensive, say an Opteron, and OC'd it past Fx-62 speeds and save $500 dollars, stuff like that would bring it back down, approximately 500-700 dollars less.
