yeah but 3.4 3770 is not K? It is 3770 without "K"? Any differences ? only clock yes?

the 3770 isnt a K model, means that it has limited overclocking, but will possibly have a lower resell value. so if the sandy is 2600K or 2700K go for sandy, or even buy a 3570K which is i5. not much of a difference.

yeah but requirements of RAM is the same ( i mean 1600mhz and Mobo for example )? Between 3770 and 3770k.


and

I am actually a bit confused I under stand why the k is this but why does the chip lack other features



3770 has

intel SIPP
intel vPRO tech
intel VT-d
intel TXT

while the 3770k does not SO what is it?

true, but as i said the K states an unlocked multiplier which makes you overclock more&better. also, when upgrading you will sell the K easier and possibly for a little higer price, since not much people buy the locked one when they can buy the unlocked one. also, there isnt much difference, around $20-25 so it is a better choice. but if only going for gaming, the 3570K and a nice cooler such as the H60 might be better and cheaper, while there wont be a huge loss in performance.

Can somebody explain me what is BCLK ? I have read something that BCLK on 3770 ( without "K" ) can raise PCI-E clocks? I am little worried about this. I dont want to damage GPU:/ PLease explain me

Have you overclocked on your current P55 platform? If you have you adjusted the BCLK, on that platform BCLK was 133MHz, and everything else would run at a ratio to the BCLK. On SB the BCLK is set at 100MHz, and everything is linked to it, ie also runs at 100MHz, so there isn't much wiggle room before you get into dangerously high, say PCI-E bus clocks.

That is why on SB, if you want to OC, you buy the K processors, the multiplier is unlocked, so you can leave the BCLK @ 100MHz, and set the multiplier to up to say 45-50 to get a nice 4.5-5.0GHz OC depending on how good your CPU/Cooling are.

[edit] You can still OC the BCLK slightly on the SB platform, but above 105MHz on the BCLK probably isn't a great idea.

OP you have a Z77 board, go with 3570 or 3770 (with or without k)
Ivy Bridge has newer instruction sets, a better memory controller, and is faster clock vs clock than SB.

If you Overclock get the (K) if not don't worry about it.
Ivy runs cooler overall than SB, it ouputs less wattage = less heat. Only when you do high overclocks does the CPU Coolers have problems removing the added heat from the chip. (thermaldynamics!!).

Ivy also has HD4000 which is pretty good if you opt to use that, either for video, Lucid, or encoding.
The chip can also Turbo on ALL CORES as opposed to SB which turbos on 1 core.

Ivy is better if you are on a Z77 motherboard.
