If you were to buy a system now, I'd definitely get the i7 2600K Sandy Bridge. However, if you can hold out a bit without dwelling into waiting syndrome (if you continue to wait forever, you'll see better and better things coming out, of course, but you'll never have anything...), the true power of Intel's new processors will be shown later in 2011. I think the second half though so it's still a while. You'll be seeing a new set of new generation CPUs with six and eight cores as well as quad channel memory. In my opinion those are the ones truly worth waiting for!
Another good thing is that AMD will be unleashing their Bulldozer CPUs at around the same time so you'll have a better range of choice regardless.

Personally I have brand new factory sealed i7 960 (3.2Ghz) that i bought about month ago. I decided to attempt to sell it to buy SB but if it doesn't sell soon enough i'll just keep it with no regrets cause with SB i wouldn't gain much performance anyways.
used a 1366 i7 950 4ghz.
its just I liked to get the new tech and 5ghz is more fun.
I had a old x58 MB so I desired the usb3 and sata and it just made sense to go sb.

So are we saying then, that for a full time video-encoding system that I will be building in 6 weeks, that I should be staying with an i7 950 or going to a 2600K on the Z67 board?

My reading to date has been leading me toward the Z67 board-2600K combo as being significantly superior.

If this is not going to be the case... I might as well get on with the build now and not wait.

for a new build right now you should go SB.

the only reason to go 1366 is if you get a tremendous deal on the cpu & board.

Raw CPU Power: A 2500K is about the same as an i7-930 in folding. That's better than any Core 2, but about 75% of an i7-870 (socket 1156). Threads matter, and 2500K does not have them.

Overclocker Sandy Bridge chips overclock on air up to about 5 GHz. Say, 4+ GHz at near stock voltages (you do want your chip to still work in a year, I presume). Takes about 2 minutes to bump the multipliers, and you're off to the races. Tradeoff: you have to buy a P67 motherboard and a K-suffix chip; you lose the neat video transcoding QuickSync capabilities available in a no-overclock-allowed H67 motherboard with integrated graphics. Or wait until February when the Z67 motherboards come out that support integrated graphics and K-sufffix overclocking. Confused? Yes, Intel did fog that up.

Video Processing Sandy Bridge, for sure, for video transcoding recorded TV down to iPhone, for example. Transcoding is hardware-assisted on Sandy Bridge. But socket 1366 for serious video editing/processing applications that need more memory, memory bandwidth, and hyperthreading.

General Multitasking Sandy Bridge is like a turbo four-cylinder to the V8 of Core i7 and the V12 of a 980X Gulftown.

Hope that helps,

Thanks...

It was Catalina588's points that I've quoted that made me question what I'd pretty-much decided on as a path.

If I go SB... it will be 2600K with 2 x 4Gb 2000Mhz ram for a start, maybe even 4 x 4Gb, and again... the machine will be a purpose-built video encoding PC in a situation where a 970/980 cpu cannot be afforded.

SB will do you fine for the reasons you will be using your rig. There is no gaming performance increase with the 6-core (so in other words, save your money )

...NO! The difference is sooooo minimal you will not notice the difference. Just take some time and read this...AMD Radeon HD 5870 PCI-Express Scaling or GeForce GTX 480 PCI-Express Scaling. There are also other articles related to this regarding SLI/Xfire configurations...just Google it

Honestly, all you need is a 2500K if your build is strictly for gaming & video-encoding. HT is not going to do anything special for you and for video-encoding, the performance difference will be minimal when compared to the 2500K. Check out the reviews for these processors & you will see for yourself.

Regarding to memory speed, you should save your ca$h & stick with 1600MHz Cas 7/8 ram. The memory speed will have no effect with video-encoding or gaming at the end of the day. Take some time & read this...Bit-tech's Article: The Best Memory for Sandy Bridge

Read, research, & don't be afraid to ask for proof...The long travel becomes more enjoyable when you see & learn more

Thanks drB

I guess I'm liking the sound of a nice cool overclock to 4.4-4.6ish on air (hence thinking the 2600K is the way to go), figuring that it will have to increase overall performace despite being almost at stock settings., and with pricing of Ram the way it is... a kit of 2 x 4Gb 2000Mhz ram is fine, with the opportunity to go to 16Gb later if it's going to make a real difference.

edit... having now read that article you linked (awesome article btw)... I'm thinking of lower Mhz & tighter timings is the way to go.

Thanks again

When I was shopping for a motherboard/processor 6 months ago and doing my research, I was under the impression that the 1366 chipset was superior, not only because you could only get an i7 on the 1366 at the time, but that there was a really bad bottleneck with the PCI-E lanes. I went with a 930 as a result. Were you planning on doing crossfire/sli? Has anyone here mentioned the chipsets themselves and their pros/cons instead of just comparing the two CPU's? While SB may be superior in some aspects compared to a 950 your motherboard may hold you back as well.

I would say go with the SB. Also I wouldn't plan on those EE CPU's to come down in price THAT much unless you buy used. Just look at the older Core2 EE, they are still selling for significantly more than even the newest non EE i7 chip. GL with your build

Definitely only a single card.

Haven't seen any discussion about boards bottlenecking, but I'm sure someone will have considered it somewhere.
