I have an ASRock Radeon RX5700 Challenger 8GB with Overclocking. It’s GDDR6 memory with a boost rate of 1725MHz. It’s got dual fan cooling on it and I believe it can get up to 88c. It works great at 1080p and decent on 1440p, however I’m on a 55’ 4k tv and had to get a more powerful GPU. This will be a great card of your on a monitor though. As for condition there is not option to say it’s like new, but it is. I only used it for about a month with no problems. The only thing is that a couple of the cooling fins are bent, but the people who built my pc said that won’t cause any problems and it didn’t. Unfortunately I was dumb and didn’t take a video of it working before I swapped it for my new one. If you don’t have your own PC to test it in I AM offering a money back guarantee if it doesn’t work.
