Question

New pc for Canon 4K 300Mbps

I am in for a new pc.

My i7 940 still runs fine but 4K is a bit slow

Will this do?

ASUS PRIME X299-A

Intel® Core i7-7800X, 3,5 GHz (or 8 core for Pr, dont do much AE).

ASUS GeForce GTX 1060 DUAL 6G (or do I need the 1070?)

RAM 64 gig

C: Samsung 850 Pro, 256 GB SSD (all ready in my old pc)

😧 Samsung 960 EVO, 1 TB SSD m2 (project and media)

E: HGST Ultrastar 7K6000, 4 TB Hard disk (the rest)

Thanks and a Merry Xmas to all.

    Ann,

    There is currently little reason whatsoever to buy that i7-7800K, especially since the platform will cost you more money total and perform slower overall than a PC platform based on the new i7-8700K and a Z370 motherboard. The i7-78## series CPUs give you only 28 PCIe lanes from the CPU (instead of the 44 PCIe lanes on the i9 CPUs). So if you must go for an X299-based system build, I would suggest spending a bit more to get the 8-core/16-thread i7-7820K instead of that 6-core/12-thread i7-7800K (which, by the way, is more powerful overall than your current system but not sufficiently so to justify its cost - in other words, it delivers a relatively lousy performance-to-cost ratio by current standards).

    On the other hand, I would not go for the higher-end CPU if that forces you to downgrade the GPU to a GeForce GT 730 or worse. But even so, there are better ways to spend 500 to 600 Euro than the i7-7800K/X299 CPU/motherboard combo.

    Thanks for inquiring,

    Randall

    Thanks for the info: now you got me confused.

    I would like a system that will last me a couple of years. (my current one is from CS4 up to 2018)

    HD is ok but 4K is a pita. I dont want to use proxies as I use the Warp Stabilizer a lot.

    Do i read between the lines a i7-8700 and Z370 is the way to go?

    Bill,

    There is no free - or even expensive - lunch, in this case:

    Due in part to Intel's mere evolution instead of a true revolution in CPU performance in the years since Sandy Bridge came out back in 2011 (caused in part by AMD's lack of a truly competitive CPU during most of those years), the current CPU trend is either high base and all-core Turbo speeds but low CPU core and PCIe lane counts, or high PCIe lane counts but extremely low core counts and/or base and all-core Turbo speeds. And in Intel's new super-expensive CPUs, Intel tended to put more CPU cores at significantly slower base and all-core Turbo speeds in its fully-PCIe-lane-featured CPUs instead of increasing the base and all-core Turbo speeds. In other words, the new editing system buyer is stuck between a rock and a hard place.

    I wonder if anyone is adding any of the PCIe expansion chips like I have in my X99-E WS, you can run 4 GPU's at x16 in it

    Where can I download a sample of your media?

    The only thing i can add is that i once had a GTX 980 and render out 4K media with GPU filters on took very looooong time. I then replaced the GTX 980 with a Titan X (Pascal) and did cut render times in half on the very same computer by just changing grapic card. This was before the GTX 1080 Ti hit the stores.

    Yes, they are from different GPU generations but what i learned was is that buying the best card can pay off. If you have the budget, aim for the 1080 Ti if you use GPU filters with 4K footage if shorter render times are preferred. You really want as many CUDA cores as possible.

    I would have add another SSD disk as well. Render from an SSD to another SSD is really nice depending on format. H.264 not so much, CineForm/DNxHQ yes please.

    Some will disagree.
