I7-3820 vs 3770K

Looking at a new system. Mixed work/play. Lots of email, browser windows (30-40 at a time), VMWare workstation with 3-6 VMs running. Lots of office app windows open, Photoshop, Music, streaming vid sometimes. No significant gaming.

I generally keep a system 4-5 years then replace, very rarely upgrade except to add RAM or Disk. Cooling is a big issue; hot here in AZ and I want to minimize thermal failures. Thinking disk IO, RAM, and video are most important for my uses.

Almost pulled the trigger on this: i7-3820, ASUS P9X79, 32G quad RAM, M4 256g SSD for OS, 1tb WD blue for storage (also have another file server for doc/photo/audio storage) of VMs and temp data, HAF XM case, Corsair 750TX, GEForce 560.

But then saw some reviews/comparisons with the 3770K. Looks like the 3770 might be a better performer, but don't see much that directly addresses my type of use.

Thoughts please? I'd like to keep the 32g ram and drives/case/ps specs. Not sure which Mobo to choose. Been an ASUS fan; built several with those and never had a problem, but don't know much about the 77 series mobos.

Also wondering if the onboard graphics are good enough to dispense with another video card? 24" mon, 1920x1200. Might want to add a second monitor. Wondering if the 560 is better than the onboard? Maybe use the 560 for main mon, onboard for a second older 19" mon I have...

Might build myself, might just get one from Magic Micro. If I use them, I eliminate any DOA components but it costs a hundred or so more...

Thanks in advance for any help...

They are going to perform essentially the same for just about any task. The LGA2011 socket it supposedly higher end, but it is also a little older chipset. You also aren't going to get a fully unlocked chip if you go 3820, if overclocking is important. You will probably get higher RAM capacity with LGA2011, so that might matter for VMware.

Honestly, it likely isn't going to make a difference which you pick for the CPU.

Video card, the GTX560 is going to be a big step up from the on board video and essential if you do anything 3D. IF not, the onboard video is quite capable. But for a high end build, I'd at least grab a $100-150 graphics card for general performance. GTX 560 is a bit outdated, so I'd likely go 7770 or GTX650 Ti instead.

And if you do get a video card, run both monitors from it. You won't gain anything by running one from onboard and any video card is going to come with two or more monitor ports.

i7-3770K + ASUS Z77 V Pro + GTX 560 (not outdated and perfect for your needs), outperforms the GTX 650 Ti and battles the HD 7770.
I recommend something like this than a LGA 2011 (i7-3820) build.

3770K over the 3820 any day.

the 3820 is what is leftover from x79 and has the most problems with it.

Browse to anandtech.com, get to cpu benchmark compare with those 2 models, 3770k is better then 3820,
The only advantage of 3820 is the 2011 sockets, u can upgrade it in future, probably 6 core ivy bridge-e,

But since u only upgrade once in 4-5 years like me, u might want to consider the 3770k, and buy a new rig in 2016-17,

Good Luck.

GTX 650 Ti > Radeon 7770:

But you are right about the GTX 560. I was thinking of the 550 when I made those comments. But a GTX


I still say it probably won't matter which processor. The benchmark differences are in the "you won't notice unless you pull out the stopwatch" range. By I probably wouldn't use LGA2011 unless you want loads of RAM or plan to use a high end 6 core at some time in the future.

So I'm getting convinced about the 3770 vs the 3820, but that's bringing up more questions. 3770 or 3770K? And which mobo? If I go with the ASUS p8z77, I'm not convinced I need anything more than the V model; the others have wireless which is not a factor for me. But the SSD caching might be something worth looking at; any thoughts on that?
Also, I can't justify/afford a higher end video card such as the 650. IS the Radeon 7850 worth a look? My last 3 systems have been nvidia.
Thanks!!!

3770K + ASUS Z77 V = win in my book.
clock the 3770K @ 4.0GHz (that's all you really need and if that, but since it's a K series processor it's a shame not to clock it some...)
sacrilegious..

as for the graphics card, if only going as strong as the HD 7850 then look at the nVidia options like GTX 660.

I don't thinl nvidia can touch the 7850 with current pricing.

If you want to have the option of going to 48-64GB RAM in the future, you would need an LGA2011 board and CPU since 32GB is the most likely to ever be available on LGA1155.

if you want more ram than a 2011 just get a xeon server mb. Buy to use now not for some upgrade in the future that you will never do because by the time it matters the rest of the system will be outdated and you will want new cpu etc. Go with 3770k now, by the time you need 64 gigs used socket 2011 mbs will be in the 5 dollar bin so you could just get a used one.
