First of all......Q6600 rules....period.
65nm vs 45nm...power consumption???? cmon man, we arent bothered about the electricity bill......the fabrication process just makes it more energy efficient....and lemme be clear, 65 nm isnt too high either...not very long timee ago did people happily 90nm processors and were happy with that
CACHE SIZE MATTER.....A LOT.
8mb hits the sweet spot in terms of performance.....Q6600 is every overclocker's dream proccy man..fith the budget and gives the performance like a mad dog....
but the only thing is that it's ideal for multitaskers and video editors...
if ya want to get into gaming then a core2dou (e8400) would out perform Q6600 in terms of FPS. This is coz of the fact that games can utilize 2 cores very very efficiently...
for any other matter than games, go for Q6600...and dont be turned down by the stock speed of 2.4Ghz....it can be OCed to a cool 2.8Ghz with a decent cooling solution...
Go for the Q6600 man...it's really cheap at 10k....it's already so low priced coz of the the Q9XXX series by Intel that you dont need to think twice...
