One nice feature of the 1060 FE for SFF enthusiasts is how they've chosen to handle their six pin connector. Makes me want to buy one ASAP
Also to answer the OP here, have you considered waiting to see what the RX470 looks like? Apparently it could be closer than it probably should to RX 480's performance with a lower TDP and considerably lower price tag as well as what looks to be an ITX length reference design.
If anyone sees either the Zotac or EVGA short form GPUs come up, please let me know. So far nothing I can find anywhere.
Between 0% and 20% faster than the RX480, depending on the game. Price is 20% higher than the RX480 though.
It also offers the advantage of lower power output and thus reduced noise. I feel like the upgrade from the RX480 to the 1060 can be well worth it, especially with ITX cards where you only have one fan to cool the whole thing.
The lowered power consumption is also interesting for FlexATX users where more power output means more noise.
In Europe the price difference is much lower, too. The RX480 4GB goes for 249€ if you're lucky, the 8GB is 269€. The GTX 1060 starts at 279€. 30 bucks more for higher performance, 2GB more RAM, lower noise and lower power consumption? You bet I'd buy that.
