*Notice: Please for once I don't want any 100% references to a "gaming computer", I have asked questions like this before and I always get "gaming frame rate would be..." Types of answers. If you post would you please regard this as a video rendering Rig 1st THEN any insight on gamin framerate, cons/pros, etc. is gladly welcome/encouraged: Thank you!*

So anytime I ask about the i7-2600(or 2700)k processor I always hear great things and I think i'm going to get one of them. However, I hear great things in terms of Framerate and gaming stuff. My GPU is a 7970 BTW so I know it can run any game on ultra w/ enhancements mods just fine with an i7-2600k. But never on the Video Rendering side.

How does it preform for rendering Hd videos?
Would it be good for say a 5 minute 1080p Hd video on After Effects? or take like 2 hours?
How much better would it be if I had a 3930k? since it's six cores instead of 4?

I hear adobe programs can render video's faster with a Nvidia GPU but I want a AMD 7970 since it's a good bit better than the GTX 580. And I figured you could use AMD since it's a leading graphics card brand with the Adobe GPU Acceleration technology in After Effects. <-- I dunno if any of this is true or just random ranting lol but any insight would be helpful.

Also how much Ram should I get for video rendering? I was planning on getting 8Gb but I hear people needing 16Gb or more? The 8Gb is the DDR-1866 or whatever not 1600, or 1366.

Please help, I'm trying to work around my $2050 budget including monitor, case, and everything and just balance everything accordingly.

Thank you very much, have a nice day!

It seems you´ve got a lot of info regarding CPU peformance already, but you may want to have a look at CPU charts for Video Editing in Adobe After Effects CS5 http://www.tomshardware.com/charts/desktop-cpu-charts-2...

By using the above tool you can compare CPU performances, which gives you a lot of parameters to help you to get the right CPU for your needs.

If you are in interested in other CPU results, like audio/image rendering and so on and forth, then go to this link http://www.tomshardware.com/charts/desktop-cpu-charts-2...

Please note that there won´t be a reference for the 3930k in above charts, however in theory it should performance better, than older platforms.

GeForce GTX 580 vs Radeon HD 7970 http://www.hwcompare.com/11290/geforce-gtx-580-vs-radeo...

Mind that rendering demands a lot of writings operations, so you should be wise by getting a nice SSD for your rig http://www.tomshardware.com/reviews/ssd-review-benchmar...

I hope it helps.

you can try this page:
http://www.anandtech.com/bench/CPU/42
i only included the blender bench. you can compare using other rendering tasks.
  • mainstream cpu for rendering: i7 2600k, 2700k
    notes: 16 pcie gen 2 lanes. pcie controller built in. supports ddr3 1333 ram by default. higher spec ram can be used with xmp.
  • enthusiast cpu for rendering: i7 3820, i7 3930k
    notes: pricey. motherboards are pricey as well. supports quad channel ram. supports 40 pcie gen 3 lanes.
  • cheap(!) cpu for rendering: amd fx 8120 or fx8150.
    notes: power hungry. has 4 modules and 8 cores. natively supports high speed ram. compatible with 990fx chipset which supports 32 pcie 2.0 lanes.
    for rendering 16 gb ram would be better than 8 gb. 1600 should be fine.
    adobe supports some nvidia geforce cards for gpu acceleration.

    Depends what programs you are using.

    if you are using the Adobe CS5 programs, then it would be on graphics performance, because those programs in the CS5 bundle work and render from the power from your video card.

    If I was you and you wanted graphics, I would go for a Core i7 2600k atleast or a 2700k. And start looking for a good graphics card.

    I would recommend Nvidia graphics cards for video editing, because they have a feature called CUDA, which helps your rendering process faster.

    here is an review of the sandy bridge-E Core i7-3930K
    http://www.bit-tech.net/hardware/cpus/2011/11/14/intel-...

    only dual processing like x2 Xeons outperform it the Cinebench R11.5 benchmark
    http://www.bit-tech.net/hardware/cpus/2011/11/14/intel-...

    for multi tasking along with video editing those 6 cores along with as much RAM as you can muster might be the platform you would benefit most with.

    now before going off the deep end; how much video work do you expect to be doing? if this is more of a hobby then the i7 2XXXK would be more appropriate.

    and yeah nvidia has the cuda technology, which really shines through in their Quadro cards but very expensive.

    serious video workstation; sandy-e and quadro
    hobbiest: i7 sandy with a Geforce card.

    Also, need some good fast RAM. 16gb 1600-2000Mhz is good.
    If you wait for the new IVY-BRIDGE CPU's then it will be Quad Channel, which will be incredibly fast memory.

    16gb of 1333mhz will be perfectly fine, as said before if you do not remember. Ram is not used as much as the graphics card (Open GL) is to preview in adobe after effects.

    Not on all motherboards, only on some.

    all the 2011 socket motherboards used Quad Channel Memory

    Im relating to Ivy-Bridge CPU's

    When they come out for the 2011 socket.

    There are only 3 Sandy-Bridge processors out at the moment for the 2011 socket, well in Australia there is.

    Also with DDR4 memory coming out next year, alot of the motherboards will be changing.

    I do not have a precise and knowledgeable information.
    All I can say is that actual video associated to the processor are not worth my attention "yet", especially if I already have a OK graphic card.
    The second point is that there is a new set of instruction on processor called AVX that would make you greatly benefit in worklow and perhaps speed rendering for at least 2D/3D application like After Effect from what I read in various articles; therefore AVX instruction on processor would be my targeting processor line if I were you.
    Best thing,
    Google and type Intel AVX, that should give you a better lead.
