out of the box the gigabyte has a higher clockspeed, also the windforce cooler, which i also have on my gpu does a better job at cooling the card because it is no tri-x version from saphire (windforce and tri-x are comparable).
also the gigabyte has 1 dvi-i dual-link 1 hdmi and 2 minidisplayports while the saphire has 1 dvi-i dual-link 1 dvi-d dual-link 1 displayport and 1 hdmi port.
keep in mind tough that the gigabyte is 11,18" and the saphire 10.31" so make sure it fits
