Much like the MSI announcement I just posted, ASUS as well will be offering a GeForce TX 1060 and 1080 STRIX with faster memory. They tag them as OC edition.

The GeForce GTX 1080 STRIX OC has 11 Gbps GDDR5X memory (ROG-STRIX-GTX1080-O8G-11GBPS) and the 6 GB GTX 1060 STRIX OC (GTX1060-O6G-9GBPS) now has 9 Gbps GDDR5. The 1080 SKUs will get its memory at an extra ~10% in memory bandwidth. Unless the boards are clocked faster, we doubt a little if the increase in memory frequency will have a substantial enough performance increase.

The STRIX GTX 1080 features triple-fan DirectCU III cooling solution, which is 2-slot in design. In terms of circuit design, we are looking at 8+2 phase power delivery with 6+8pin connectors. It is a bit unclear when these models will be available, we expected them this week already TBH. However it seems that will be early April then. Prices have not yet been announced.
