Gigabyte Radeon R9 280X
 

There is a review of the Gigabyte Radeon R9 280X posted today at Legion Hardware. The Gigabyte version had no problem matching the thermal performance of the IceQ X² and was in fact a degree cooler under load. Another fact to consider is that the Gigabyte R9 280X is around 4cm shorter which should help it fit into smaller cases. Last but not least the Gigabyte version is the most heavily factory overclocked R9 280X we have come across, with a boost clock of 1.1GHz.
