as of now i plan on getting the E6300 and Bigwater 745....and i think i will be OCing the beast.
No need, they don't really get hot...you could probably do the same with a high end air cooler, which I think I'll do. I personally plan on getting a Gigabyte GA-965P-DQ6, 2 gigs of cheap ass ram, an E6300 and salvaging what I can. Hoping for 3.6ghz on air, seems more than doable as some already have gotten 3.8 on nice air cooling.
BTW, as for your question, just look at the clockspeeds. the E6300 is only about a hundred mhz under the X2, but the architecture is much better. Also, the Conroe has a lot more overclocking headroom, whereas AMD has next to none (well, maybe 1000more mhz...but with Conroe's hitting 3.8ghz on air, what's the point?)

I think that you will never reach 3.6GHz on air. It is almost +100% overclock. +50% is more than excelent, 2.8GHz.
I am after E6600 2.4GHz 4MB L2. I hope to reach 3.2GHz stable.
The E6300 will clearly leave the X2 3800+ behind but you will pay slightly more because 775 Mobos are very expensive.
Well, they are not more expencive than those for s939, but not that much. The reasons are that more lanes are used for DDR2 implementation than for DDR and the more expencive chipsets for Intel(counting on the IMC). The K8 DDR2 mainboards will be more expencive than the K8 DDR. The K8 needs faster(more expencive) DDR2 than Core2. So there is a compromise between the RAM and mainboard prices for both systems.
But the Core2 will wipe the floor with X2 and will cost less.
Some people got higher clocked E6600 to 3.6 on air, with rather warm room, I wouldnt be that surprise, if with more mature motherboard and good ram, you can hit these sort of speed, granted not at 1:1 because that would be a 500mhz+ FSb and the most I saw was 495 with a moded 975XbX
Finnaly I agree that for a day to day overclock, 2.8-3 seams more reasonable!
Personally I would shoot for a E6600 @ 9X 266=2400 and run it at 9X400=3600 with DDR800 1:1
Not much of a compare to an X2 3800+ but this chinese site pits a E6300 and an E6400 against and FX-60 so you have a vague point of reference. Do your own interpolations, they will be mildly and I emphasize mildly accurate, more like round ball park but not much more.
Anyway, I plan getting the E6600 and using a Scythe Ninja to cool it passively. It should be doable since the TDP is much lower than the Pentium 4 D series. Of course caution is must. Hopefully www.silentpcreview.com will have an article on it before I experiment with it.
