Word has it that Asus will showcase its GTX 595 Ares at Computex 2011. The dual-GF110 card is rumoured to have clockspeeds even higher than those of the single-GPU GTX 580.
Whereas the GTX 590 was clocked slower than the GTX 580 in order to accomodate two GPUs, it is rumoured that the GTX 595 will be even faster. Reports say that Asus' GTX 595 Ares will be clocked at a whopping 875MHz (shader clock 1750MHz), with a memory clock of 4800MHz. Memory size is most likely 3GB (1.5GB x 2). If this is true we can expect another Very Large Card from Asus.
