[M] HIS R9 380 IceQ X2 OC 2GB Video Card Review
 

HIS has currently two R9 380 video cards available for sale, one with 2GB buffer and the other with 4GB of GDDR5. The 4GB version is sporting the same core clock frequency, but the memory runs just a little bit higher and to be more exact 1425MHz. Considering that this card was designed for the mainstream segment, people won’t throw at it games at ultra-high resolutions and even if they would try in order to fill the extra 2GB of buffer, the GPU core won’t be exactly able to keep up reasonable FPS. The card performs well in the Full-HD area but if we would like to run games at 1440p, we should consider fiddling with the detail levels.
