The 580 uses the same die, but binned for required frequency/voltage/power, and for the chip to be fully functional (a 570 has parts of the die disabled, such that dies with some defects can still be used). I suppose it's possible that some 570 GPUs actually met all these requirements but they simply needed a 570 rather than a 580, but I have no idea how likely that'd be.
So even if you were able to successfully flash a 580 BIOS, there's no guarantee your chip is actually capable of performing like a 580. And if there was any issue with the flash you could end up with a bricked card and I'm not sure if you'd be able to recover it.
I wouldn't risk it.
Sorry for the delayed reply, but I agree, just keep it as it should be. My mainboard only has one PCIe X16 slot and one PCI x1 slot, my CPU is an E3 1230v2 which supports 16 lanes of PCIe. If I plan to use a riser on the PCIe x1 and connect the same GPU I currently have, will it improve performance? And even if it does, would it be worth the extra cost of two times the electricity bill?
I think crossfire needs a minimum of x4 per GPU, which means it won't work. Even if it did, people say multi-GPU support is bad and declining, making SLI/crossfire less useful.
