Looking for advice for gaming PC

That's a really powerful computer for gaming. The 1000W power supply is overkill you'll never need. The 850W is about 400W of overhead on that system.

An AMD CPU with more cores will not improve gaming performance. You could get the fastest gaming chip out now with an Intel 11900K and an Asus ROG Maximus VIII Hero motherboard for $154 more with everything else the same. The price differential is all in the mobo.

You don't say the monitor resolution you are aiming for. At these prices, you shouldn't want to overpay for what you need. At 1080p, the 3060 Ti is killer. At 1440p, the 3070 is right. The 3080 will max out 1440p and game very well at 4K. The 3090 is for masochists who must burn money. It's a $1500 card going for $2900+. The Nvidia cards get the edge over the very solid Radeon line IMHO because of Deep Learning Super Sampling (DLSS), and a more mature ray tracing tech. It's not much, but it's an edge.

You deselected internal lighting, so....

I wouldn't change anything else. You'll never see much difference with the Intel chip, but you will have bragging rights for maybe 8 months. The CPUs are overpowered strictly for gaming these days, so getting an edge there doesn't mean a whole lot.

Either CPU/motherboard choice would be considered very strong for a gaming rig, and will easily last 5 years without hindering your performance. The Intel 11900K is the fastest you can get now.

Happy to help.   

sound good THanks man
