Read first: Will PCSX2 run fast on my computer?

[SpiffyJUNIOR]

What tends to be more important? Core amount,or GHz?

[jesalvein]

Ghz.
but mostly STR

Thank god i built a custom loop for OC.

[jesalvein]

Still. It mostly depends on STR.

Will this run it at full speed?
i7-6950X(@4.5GHz)
Custom EKWB Loop
ASUS Deluxe X99 II
Corsair LED 32GB (4x8GB) DDR4-3000
Zotac 1080Ti Extreme AMP
Windows 10 x64 Home
2x Dell-S2716DG 2560x1440 144Hz

Single threaded performance is not just GHz (unless you are comparing a skylake i5 to a skylake i5, or other equivalent CPU to CPU). The microarchitecture from the cache to the instruction pipelining to branch prediction and the rest all add up to differences at the same clock rate of how efficient the CPU can use each cycle.

example
an i5 6600k at the same clock is about 7% faster in single threaded performance then a i5 4690k

Generally newer CPUs will have better IPC (instructions per clock) and therefor better Single threaded performance Clock for Clock then older chips from the same manufacture.... but due to there being tradeoffs between valuable chip space and thermal/power limits this has not always been the case for all newer chips and all manufactures.

It should handle most games at full speed. (there are some really demanding edge cases that just don't play nice) You should also be able to enhance your games above what the PS2 originally was capable of (again not every time but most times)

Jak II,here I come!

Yeah, jak 2 should do fairly well on that. Might have some slowdowns, but it should be decent overall.

What about R&C1,2,3 and GT4?

Those should do well for the most part
