$294 very ok la.
It will out-perform 2600k in software like Photoshop CS5 with its quad channel ram.

no

2600k can oc while 3820 cannot

Sure if you take OC as an adv of 2600k, while personally I insist on sticking with stock freq.
And is it really freq dependent on tasks like Photoshop CS5?

I have heard that a i7 950 can beat 2600 in CS5 with its tri-channel ram, it looks Ram speed can be the bottleneck of performance in some cases.

Oh, you are correct, even in CS5:

photoshop最重要係freq, 之後先到no. of cores...

I see, I did heard someone claiming that the no. of ram channels made a difference for CS5(not 4),
while I cannot remember where I read that.

It was once forwarded by me to this forum.

都唔出奇... 但係相信影響無cpu freq咁大

That's what makes me think that SBE 4C8T w/ quad channel rams can be favoring some specific tasks that i7 2600 may show its weakness at.

For it being priced the same as i7 2600, no doubt it is a new hot cake for computer builders, while some may stick with 2600k for its overclock-ability.

so little tasks benefit from extra memory channels...

Looks confirmed for SBE without HSF,
and high end BD will be having liquid cooling......

No OC multi =/= no OC bus.

Video editing.
Why CUDA can do much faster than CPU, one of the reason is RAM bandwidth.
