I recently picked up an RX 9070 XT and paired it with a Ryzen 7 7800X3D, and I'm kind of concerned about the performance. I'm using a 180Hz monitor at 1080p, and when I jumped into GTA online, I was only getting around 100 to 110 fps. I've watched some benchmark videos where they hit over 150 fps with similar setups, so I'm wondering if this is expected. My full build includes the CPU and GPU combo, an ASUS TUF Gaming B650 Plus WiFi motherboard, 32GB DDR5 6000MHz RAM, a 1TB SSD, and an NZXT 750W Bronze PSU. I'm suspecting the power supply might be an issue since it has daisy-chained PCIe cables, but I can't replace the cables because they're all plugged in. I've tried uninstalling all drivers with DDU and reinstalling the latest ones. Any advice on whether I should get a new PSU or something else?

The RX9070XT is a very sensitive GPU that requires some commitment of the user in order to find the right settings. Every setting in the bios that has not been optimized for this GPU will crash the system or, in a best case scenario, cause performance degradation. Start by making sure the timings of your ram are EXACTLY one third of the timings of the GPU's VRAM (And yes I know the VRAM timings fluctuate so your RAM has to do the same thing in order to keep everything synchronized) Please do not think that a minor Bios setting like USB legacy mode on or off won't influence the behavior of the GPU. EVERYTHING must be set just "right" If you have a black screen or driver timeout you know "something is not right" Keep on tuning till everything works and don't forget to have some fun tuning your system. Believe it or not but the GPU will detect feelings of hate or other negative energy coming from it's user and, when detected, a crucial BIOS setting might just change spontaneously into a value that will slowly burn your processor or fill up the HD with garbage. PS buying a new PSU is always a good start. These GPU's like fresh PSU's, they eat them for breakfast.
Just to confirm, make sure your monitor is plugged into the GPU directly and not the motherboard. If it is, that’s great! Also, did you clean out the old drivers with DDU before switching to the new GPU? Sometimes remnants can cause issues.
Hey! First off, make sure to check the specs of those benchmark videos. They often use custom settings and might not be running in a case. Also, if you upgraded from an NVIDIA GPU, it's a good idea to clear the shader cache, as your games could still be using old NVIDIA settings. Try MSI Afterburner to see your GPU's power consumption—if it's low, you might have some undervolting going on. Lastly, double-check if there's an 'X3D gaming mode' in your BIOS that you're missing!
Thanks for the tips! I did come from an NVIDIA GPU, so I’ll look into clearing the shader cache. Saw the power consumption was under 90W while gaming, which does feel off, and I’ll double-check the BIOS settings.
Have you looked into your power supply setup? A 750W Bronze PSU should handle your build just fine unless there’s a fault. Daisy-chaining cables can sometimes lead to power delivery issues, so consider testing it out with a different PSU if possible or organizing the cables better if you can.
Yes, I did use DDU to remove the old drivers, just to be sure.
