I came across a second-hand ASUS TUF GeForce RTX 5070 OC for $700, and I'm curious if it would work well with my current setup. I'm worried about potential bottlenecks. Right now, I'm playing Marvel Rivals at 1080p and struggling to hit 150 FPS even with optimized settings. Here are my current specs: CPU: Ryzen 7 7700, Motherboard: ASRock AMD B850M Pro RS WiFi 6E, Cooler: PS120SE ARGB, RAM: KingBank DDR5 RGB 32GB (2x16GB) 6000MHz CL30, GPU: AMD RX 6600 XT, Storage: 2x NVMe SSD + 1x HDD, Power Supply: Antec ATOM G750 Gold 80 Plus 750W, and I'm using a mid-tower case.

The RTX 5070 is a solid upgrade, especially if you're looking to boost your FPS in games. With your Ryzen 7 7700, it shouldn't bottleneck too much since it's quite powerful. You’ll likely see a significant improvement in performance at 1080p, and it should handle more demanding titles better than your RX 6600 XT. Just make sure your power supply can handle the new GPU!
That price sounds a bit high for a used card. Just be sure to check its condition and whether it comes with any warranty. New models are coming out, so sometimes waiting for a better deal can be worth it, especially if the GPU market changes soon.

Yeah, I agree! Your PSU should be sufficient, but double-check the power connectors needed for the 5070 just to be safe.
