I want to upgrad quad 2.66 nehalem to something-6core so I have some question. 1.) Is it run hotter? (2.66x4@45nm vs 3.33x6@32nm) 2.) If i use core i7 9xx instead xeon. Are my pro get stability issue? 3.) I got ~$300 deal on x5670 with water damage, (it live under the water for ~15 days "Thailand flooding crisis") but can work properly. Are my pro get damage when using this proc. 4.) if you were me what you choose? W3680@$660+ i7-970@$450 or water-damage-but-still-working w5670@$300 Thanks.
