Dear konstantinos,
Thank you for your kindly mail and inquiry. Gigabyte graphics cards have different BIOS versions for one model. For example, VGA BIOS version F1 to F9 will be one series and BIOS version F10 to F19 will be the other series. So in theory, if your VGA card's current bios version is F10, and you see version F3 available on the website, F10 is the latest BIOS vversion of the VGA card you use.
If you still have any further question or suggestion about our products/service, please do not hesitate to contact us. We will try our best to help you resolve the problem ASAP.
Regards,
GIGABYTE TECHNOLOGY
