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]

Intel’s Core i7-9700K is an unlocked 9th generation Coffee Lake CPU. It is an 8 core, 8 thread processor. The 9700K features 12 MB of cache, a 95W TDP and Intel UHD 630 graphics. Like the other 9th generation chips, it is compatible with Intel’s new Z390 chipset as well as last years Z370 chipset (with an updated BIOS). The 9700K has stock base / boost clocks of 3.6 / 4.6 GHz and a single core boost of 4.9 GHz (compared to 3.6, 4.7 and 5.0 GHz for the flagship 9900K). This translates to almost identical single, quad and octa core performance between the 9900K and 9700K. Mainstream PC games do not benefit from more than eight threads, so at $350 (25% cheaper than the 9900K), the 9700K offers far better value for money to gamers. That said for purely gaming there is very little reason not to consider the i5-9600K which, when overclocked, offers almost equivalent gaming performance but at a 35% discount[Oct '18 CPUPro]
