I will building a new workstation and I forget how many post that I have ever read about it watched bunch of videos and finally I am so confused. I was thinking to buy i9 7940x but that CPU is really bad for after effects? If it is.. only getting render? I do not have any time issue for rendering. I just want to work on huge project like 4K-6K footage and cinemaDNG codec as a live preview. i9 7940x is really bad choose for After Effects? Or the almost the same performance with i7 8700K? everybody is choosing i7 8700K because of price/performance? I have been thinking to fix multi-core issue with rendergarden, if it bothers me So could you help me out please? I am really so confused what I need to choose http://www.userbenchmark.com/PCBuilder/Custom/S67316-M347462.251565.200815.161079.102222vsS59466-M353078.251565.200815.1…  [Apr '18 eraizgn]

MORE DETAILS

The Intel i9-9900K is an 8 core, 16 thread, unlocked 9th generation Coffee Lake processor. It has a base / boost clocks of 3.6 / 4.7 GHz and a single-core boost of 5.0 GHz (the highest frequency achieved yet from this class of Intel CPU). It features 16 MB of cache, a 95W TDP and Intel UHD 630 graphics. The 9900K is compatible with the new Z390 chipset, and subject to a BIOS update, is also compatible with the older Z370 chipset. Aimed at users who do not wish to compromise, the i9-9900K offers the best gaming and desktop experience available at any price. Heavy workstation users should consider the Ryzen 9 3900X which is similarly priced. Comparing the overclocked 3900X shows that it is just 10% worse for gaming and desktop (sub octa-core) but around 40% better for 64-core computations. Gamers should consider the 9700K which offers identical overclocked gaming performance at a $100 USD discount. [Oct '18 CPUPro]
