looking to purchase a 2011 socket cpu
i have narrowed my list to either the 4820k,3930k and 4930k
looking fleebay i recon i can pick up a new
4820k for around £200
3930k for around £250
4930k for around £320

i guess what i'm asking is what the good people on here think represents the best value for money given the prices listed

i used the prices for new above because i thought it would be easier to compare than to speculate on a cheaper 2nd hand price

what is the main use of the machine? :)
If gaming, I would rather get a i7 4790K at that similar price and a brand new Z97 motherboard that costs less than most of the decent X79 motherboards. X79 is buggy as hell.

Nah X79 isn't buggy. I have two X79 systems and they run great.

As for thread starter I'd look around for a 2nd hand 3930K or 4930K - whatever you get the best deal for.
 
Out of that list 3930K is by far the best value for money, the 4930K is the better chip in just about every department aside from raw clockspeed when overclocked if you can stretch though, but bear in mind that Sandy Bridge needs that extra 200-300mhz overclock to match the equivalent Ivy Bridge on performance - and it's going to put extra strain on motherboard/VRM's and require better cooling.

In what regard? about the only issue I know of with X79 is SB-E based CPU's not being fully compliant with the PCI-E 3.0 spec but you can always run them at 2.0 or throw caution to the wind.

Yeah that's only issue I have with x79 but I use a nvidia reg hack to make it run at PCI-E 3.0 but in all fairness makes next to no difference speedwise other than that its been a rock solid platform :)
 
Ive got a 3930K processor sat here doing nothing after a motherboard I bought was DOA. Often thought about getting a replacement board and building something up but never actually got round to it.
 
Only issue I've encountered with X79 is a start up bug my board seems to have. When overclocked it starts, resets, then boots perfectly.

And I can deal with that, given it will run my 3970x stable at up to 4.9ghz.

Not had any issues to speak of with my X79 UD3 either, and that's running an unknown 8 core Xeon.
 
I have had 2 X79 systems, the first one was Rampage IV Extreme + i7 3960X, it did not work at all with Crucial ballixtix RAM. Later I replaced it with Gskill Ripjaws, worked very well with DF or XMP setting but could not boost with manual timing.
The second system was X79 UD5, i7 3930K, Gskill Ripjaws. It refused to boost with highend graphics cards (I tried R9 290X, GTX 780), later on I found out that I have to change the PCI mode to legacy.
 
I have a 4820k and a 4930k. Both are 24/7 clocked to 4.6ghz and the only problem I've had was a dead ram slot on my rive board but got it fixed. That happens on all makes/ model boards.. just a defect. Outside of that very solid. I loooooooooove my 4930k rig. Pushes 3 gpu's much better than the 4 core. For a single gpu and not really editing or streaming? Go with the 4820k but if you are going to stream or use multiple gpus get the 4930k.

Especially for streaming.. I couldn't believe how big of a difference there was for twitch encoding :D

3930K. They can clock very well, i'm still using mine and don't see any reason to upgrade to X99 yet.
 
I have x79. My thoughts are:

4820K - Not enough cores to warrant x79.
4930K - The best CPU but not worth the premium over the 3930K.
3930K - Nearly as good as the 4930K and put the spare £100 into your next GPU upgrade or towards XFire/SLI.

Either 4930K or 3930K would be good but going for the 3930K would allow you to put more money towards a GPU in future and end up with an overall faster system.
 
thanks for the feed back guys
i was rather leaning towards the 3930k
but you comments have helped me decided on the 3930k
 
Yeah if those are the current market prices then the 3930k is definitely the one to have.

Average 3930k is equal to 4930k and if you have a good clocker (like I do with my 3970x) then you pretty much have the 5930k too as they don't clock anywhere near as high.
 
Yes, although the 3930 is a very good overclocking chip, my 4930 ran quite a lot cooler and as a previous poster stated used less current. Incidently, my 4960 ran cooler again and this is the one I have kept (and will be keeping for a long time)
