after buying the i7 975 i understand that its a bad bargain. do u know y? because i bought it for $1200 (shipping cost to my country + tax) . i thought is 920 do can be overclocked @ 4 ghz then i can easily push it to 5 ghz. i pushed it to 5.2 ghz stable ( prime 95- 24 hours). but i faced some problem with shutting down the pc. so i get back to 32x 152= 4.86 ghz. but there are many people who did 4.5 ghz using 920 do. so next time ill not buy the top end cpu. i ll not suggest u to do that.
