You have to think about whether you want more clockrate or more cores.
For old programs like pr, it does not matter how many "cores" a processor has because pr can only use one. if you want to do different things at the same time (internet, multimedia, at the same time a bluray rip and skype eg) you need more cores so that the individual programs can be distributed. are you mainly doing something with one program and that is not designed for multi-core technology then only a higher frequency will give you a speed boost.
At home I have an i3 with 3.3 or 3.8 ghz but only 2 cores and 4 threats. my laptop has an i7 processor with 4 cores and 8 threats but 2.4 ghz. For PR, HD movies, rendering in c4d and normal operation, my i3 is faster. with after effects and cubase my i7 is advantageous because these programs can use several cores for themselves...
amd is much cheaper than intel.
but many people do not like amd and swear on intel, which in my opinion is groundless. since you do not want to do any video editing, rendering or animations, you should not care.
I have a 1050ti. It can not do any miracles but it is oversized for normal operation. since this video card I can play pr with full details without lags.
