Cash only (I don't want to risk chargeback scams). 

I built this PC last year, and I'd like to sell it to put some money towards an upgrade.  5700X3D, MSI RX 6700 XT MECH 2X, 32GB DDR4 3200MHz RAM, 1TB SSD (forget what kind specifically, but it's rated at 5GB/s. Though due to the older motherboard, it's capped at 3.5GB/s), 700W PSU

WiFi isn't supported and the USB-C port on the front of the case does not work, but both of these are due to it using an older motherboard. It's not broken or anything like that. If you plan on using ethernet then you'll be fine.

PCPartPicker values this build at $1,400. It will generally handle 1080p high settings at 60+ fps. Some games like Black Myth Wukong might require dropping the settings a little bit but the vast majority of games run great. I have added benchmarks of several of the more demanding games that I own, for reference. All benchmarks are set to the high preset, 1440p and 1080p. Only change is disabling FSR upscaling. Due to image limits I can only share some of these benchmarks here, but my FaceBook Marketplace listing has a couple more.

Hitman 3 Benchmark (couldn't take a picture because it quit automatically before I had the chance): 1440p, Average 126fps. The rest of the benchmarks will be in the pictures above.
