    Grabbed this as a upgrade from my i7 6600k. Pricey but matches up perfectly to the RTX 2080.

    Yes, it is expensive. Yes, the Ryzen 7 is almost as good but if you don’t want to settle... this is your cpu.

    Runs super fast, but does run hot. I would not recommend a fan on this, go with a AIO water cooler. 4 stars since you have to add a fan or watercooler, and comes in a stupid clear plastic box, would rather have seen lower price and simple box or a cooler included instead of box.

    Do you need an i9-9900? Most likely not, in terms of games you don't see much fps gains. But still buy it.
