if ur asking me, imho its not worth it at this moment .
Q6600 is still kicking on current games .
d only problem i can see is bottlenecking the graphic card .
present graphic card is too much to be handled by Q6600 .
unless u could go for 4.4ghz perhaps >.<"
doubt u would do that for daily usage ^^,

so my vote goes to NO NO !

just my 2 cents .

well, for gaming not many utilizing multiple core .
but for future proof, i still dont think its good .
they're going to produce better proc sooner or later .
Q6600 is quaddie .
y not wait for better tech x6 later on .
probably another half year or so .
