Sapphire NITRO AMD r9 Fury not performing as it should.

[Ryan_231]

I recently changed my gpu from a GTX 970 to an r9 Fury (non-X) and it is not performing right. I'm getting 30 FPS max in GTA 5 at 1080p and the world is loading right in front of me. Even Besiege is running at 20 fps. I have checked temps and they are just fine, I also have all of the latest drivers and I have uninstalled all Nvidia software left on my pc. Here are my other specs:

-Intel i5-4460
-Corsair Vengence LP 2x4GB DDR3
-H97 Chipset
-EVGA 600 watt 80+ Bronze power supply

Thanks

Oye mate,

Sapphire suggests a 750W PSU. Perhaps your 600w bronze just doesn't have enough ass to power everything. I would use a PSU calculator, like the on one provided on Cooler Master's website, to get an idea of whether your current PSU is up to the task.
