Old doesn't mean bad

Basin Falls processors with the number of physical cores from six, like the Core i7-7800X, to eighteen, unlike the quad-core ones, are not built on the latest Kaby Lake-X architecture, but on the slightly older Skylake-X. The main difference for the worse is a lower frequency (even in the case of manual overclocking) caused by the 14+ manufacturing process instead of the more advanced 14++ nanometers. However, for CPUs with such numerous cores and threads, several hundred megahertz do not make a difference.

The power of two graphics cards

In our opinion, the Core i7-7800X is the perfect foundation for an uncompromising gaming PC with two flagship GeForce GTX 1080 or 1080 Ti graphics cards. There are two reasons for this. Firstly, eight threads are no longer enough to unlock the potential of two graphics accelerators. Secondly, LGA1151 processors allow you to connect video cards only in PCI-E x8 + x8 half-bandwidth mode. Whereas the LGA2066 platform removes this limitation.

Shock five-year plan

As a result, the Core i7-7800X is not a processor for the first time, and not for growth, but to be used here and now. As they say, assembled, works and do not think about upgrading. A computer with such a processor and two GTX 1080/1080Ti is guaranteed to be able to run all the games on ultra-graphics settings in 4K resolution for another three or four, or even five years.
