e6600 is better for rendering/encoding apps because it has 4mb cache (e6400 has 2mb). basically difference in gaming is marginal, if any at all.

You'll get a little more performance out of the E6600 stock because it has a higher multiplier (x9 versus x8) over the E6400. You'll be able to overclock the E6400 a little higher than the E6600, however, because the E6400 has less cache.


Personally, I'd go with the E6400. For the $80 difference, it's not worth the extra 5% or so of performance. I'd tuck that money away for a year and invest it in Penryn, which should get you much more bang for your buck.

Celerons had a great penalty over P4s. Don't know how a core2 behaves but if you see some reviews fs Athlon64s vs Sempron64s, at the same clock rate they deliver almost identical performance.
