Well idk but each 8800GT per nvidia should have 26 amp 12V+ and double that
in sli
my power supply supplies 2x20amp +12V rails but nvidia tends to over due
there requirements now.

good news 3rd day running without any weird issues. running amarok , FAH6
-smp , firefox with too many tabs open (nice seems firefox is 64bit yet uses
a wrapper program that runs 32bit flash)

now it seems my laptop might be heading south .... getting hard locks with
some weird ATA command errors but it seems networking stops working too at
times at first i thought a sata drive issue with one of the 2 sata drives on
the laptop but combined with networking errors and random hard freezes ,
seems to happen more if i use wifi ( its an intel 3XXX not an 4XXX series
card ) everytime i reboot or shutdown i get network-manager (ubuntu) crashes
, perhapes some of this could be from upgrading from 7.06 > 7.10 ? .....
seems might be another heat problem anyway .... guess i will have to
reproduce them in windows .... send to dell to repair
