Default went from 4.2 Ghz i7-860 to 2500k @ 4.8 Ghz

Overclocking these is fun, they are stable and easy to clock. 4.2 @ stock volts, 4.6 @ 1.275v, 4.7 @ 1.30v, 4.8 @ 1.32v. All prime95 and linx stable, still working my way up. This is water cooled, temps at 4.8 Ghz are mid 50s.

I ran BF BC2 last and there was a huge difference in smoothness from the 860 to this. Ran Super PI 1M @ 4.6 and was at 8.003 ms down from 10.5 second with my 860. Also tested COD BO and a few others. What a noticeable difference, I was really surprised, I didn't expect to see it.

Definitely worth the upgrade, it ended up costing me about $60 to do it. My ram from P55 worked right outta the gate, XMP1 picked up the timings perfectly, running 8gb 1600 7-7-7-24 @ 1.60v and 1T.

So anyways for those on the fence - and those that say i7 users need not apply - I'd disagree with ya there. Definitely worth the price of admission. The overclocking is fun, the boards are stable, just bump vcore and go.

That's what I'm waiting for Nekro... I wanna see the 2011 chipset do it's thing. Looking at a possible W/C Tri 480 setup now, so 2011 would be best to make use of it.

Unless you are made of money, then you are in for bad surprise waiting for socket 2011, there will be no cheap chips on it, Extreme Edition only for it's first few months unless you use a Xeon with no multiplier based overclocking at all (good luck on that bclock OC with Xeon SB).

I don't do multiple GPUs so I don't need the high end chipsets.

Same here. A single 900mhz GTX 580 and 5Ghz Sandy Bridge suits my needs perfectly as well.

With the current P67 chipset fiasco and recall, I think it would be prudent for all last-gen i7 owners to wait on getting a SB chip. Especially if you are running at GPU-limited resolutions anyways. Going from quad-core to quad-core also seems like a sidegrade to me. I'll be waiting for minimum hexacore Sandy Bridge Es.

Yes, and the motherboards alone will probably cost about $400. The board designs will be quite intricate and probably expensive to produce with quad channel memory.

definitely not a sidegrade. Feels night and day. I should be able to push 5Ghz with less than 1.4v. Got a monster clocker to boot!!

Looks like the upgrade is about a year out though...I had my i7 for a year and it already was time to move on.

"the new platform comes roughly in a year's time, Q1 2012, most likely January 2012 if Intel doesn't hit any delays."

Well I still believe 2600k or 2500K is AWESOME upgrade for most people even more so if they are happy about it and why not.

The chipset problem is being fixed and people will even have option to return and upgrade the mobo if desired.

Also it might be a long wait for some people waiting for Sandy Bridge performance CPUs on the LGA 2011 platform, unless they want to spent $1000 on CPU and probably at least $400 on motherboard. Provided the vr-zone.com article is correct.
