Mimimum requirements for a perfect emulation

8600K also has TSX yes, TSX is present on 6500/7500/8500 and above.

That 4.3GHz turbo mode is Intel bait, 4.3GHz is the max turbo on a single core, it can't turbo to that when you're using all. For those extra clock speeds, you need to overclock. You can easily overclock at least some 500MHz without a lot of effort, if you need more performance that is.

8600K is surely very good as well, if you want to save money then go for it.

yes i cheked here https://www.cpubenchmark.net/singleThread.html
Intel i5 8600K is really better thant Ryzen 5 2600X: 2.520 vs 2.142.  So its' better to buy an Intel even if it has 6 threads i think

I think that i will buy the i5 8600K, I can save money and in any case i have a really good CPU also for RCPS3, ok?

Ah, just another question: when i play a ps3 game in RCPS3, can i use the .iso format? If so, is it possible to use the DLC and updates for every game? Usually they are .pkg files that can be installed in a modded ps3. But is it possible to use DLC and so on also with the emulator?

thanks
