New CPU instructions

Hello there,
i'm choosing a hardware for a new PC.

Is a C1 10 uses much a new instructions set, introduced for 6th and 7th generations of Intel CPUs (and AMD Ryzen)?
I mean AVX2 and such things. Some people (programmers) it can drastically improve performance in some image-processing but is PO uses it?
Also, does C1 uses multi-threading much on editing (i know, how efficient it for Processing)?

Thank you for your experience and opinions.

  We extensively use SSE and AVX in all the newer revisions of the instruction-sets.
  
  We also make extensive use of multiple cores on CPU, and use GPU hardware as well.

  Thank you, Christian,
  so its worth get not only high-clock and multi-core but with support of new sets like AVX/AVX2

  You can't get new CPU's without those instructionsets. All part of the package.

  Beware the budget Intel Pentium and Celeron ranges. They don't have AVX/AVX2 support. I don't know how much that would hurt C1 performance.

  Dear Christian,
  firstly low-end CPUs doesn't have AVX.
  Also old i7 doesn't have it too.
  I can upgrade my current platform from quiet ans slow i3 to topmost i7, get clock speed and more threads, but not AVX.
  
  Also new AMD Ryzen CPU's have AVX implementation significantly slower than recent Intel's. But has have more cores/threads for same price.

  I think in terms of recent C1 versions (and many other process intensive applications) there would be little point in considering the lower end processors if seeking top end performance.
  
  For the typical specification of machines at the budget end of the market I rather suspect that the package of components would be likely to compromise performance overall, possibly to the point where the choice of processor becomes a small part of the performance factor.
  
  Grant.

  We support the extra instructions, because of the speed gains from these sets.
  
  We will always recommend to buy as powerful a machine as possible, thus avoiding, if possible lower end/tablet processors
