Is 200MHz a noticeable bump in real-time performance for a C2D system?

Okay, so you can get a E4300 to 3GHz using a 333FSB x9 (theoretically) with Geil's PC5300C4 4.4.4.12 RAM timings @ £111 on OCUK. I've tied that with a P5N-E Asus board and an AC7 cooler for roughly £330inc shipping.

So what i'm wondering now is...

Would the extra cost (roughly £70) for a E6400 and some Geil PC6400C4 @ 4.4.4.12 be worth the 200MHz extra overclock using 400x8=3.2GHz?

Of course there is no guarantee on how each chip will clock, i'm predominantly basing my idea on RAM timings as I don't want to buy RAM that won't overclock.

I have tried my E6600 at 3 and 3.2 and can't tell them apart... soo I set it back to 3

Isn't it better to get a E4300 (It has 9X multiplier and the FSB is set at 200 which is increased for overclocking anyway) with PC6400 and theoretically you could get 3.6GHz if you ever wanted?

I run G.Skill 2GB DDR2 NR PC2-6400 at 850MHz with a FSB of 340

higher memeory bandwidth always gives you better performnace....but I have some geil with a 6600 and running at 438x8...1:1 no probs (thats about 3.5Gz)...so ye the 6400 will give you better overclocking options if you want to try and run faster!

As Graeme43 stated, he doesn't see a significant benefit past 3GHz, so even though the overclocking options would be better with a E6400 and PC6400, a E4300 and PC5300 would be £70+ cheaper and could hit 3GHz.

you dont at the moment because not much requires two cores at 3Ghz...but in the near future I think you will notice the difference between a CPU at 3Gz and one at 3.5Gz...just a mater of time.
If your really looking at it like that then....you wont notice much difference between a conroe 6600 at 2.4 or 3.5.....so why do I and hundreds of others bother? Because you can!

Its great paying the price of an E6600 and getting the speeds of E6800 and faster

I always wind my clocks back in because I can't feel a difference.. my 6700 will do 3.8ghz but I keep it at 3.4ghz because there's just no point putting more vcore into it.

That is why I don't run my 6600 at 3.6
