Is this setup good for gaming?

I am creating a new gaming computer and I am wondering if my choices are optimal for gaming.

The parts that lack a price are what I already bought.

I was thinking about getting a Sapphire PULSE Radeon RX 9060 XT 16 GB Video Card but it apparently doesn't support G-sync so I am looking at the Asus DUAL OC GeForce RTX 5060 8 GB Video Card which I believe does support G-Sync as I don't get a warning about it on pcpartpicker. Can someone tell me if this is a mistake to get what I think is a less powerful card for G-Sync?

Additionally, can someone tell me if the 1000 Watt PSU is the most optimal when the watts needed is 426 w? I heard that you want roughly double what you need.

And can someone tell me if the Patriot Viper Venom 32 GB (2 x 16 GB) DDR5-6000 CL30 Memory is worth it? Because I think I saw that the highest memory is needed for graphic arts or something rather than gaming.

The case is just to be the largest thing I can fit in my cabinet.

I have no real budget but I am looking for good deal rather than spend as much as possible.

Thanks in advanced for any help.
