Reliable almost to a fault compared to faster cards with less memory....But must be understood in its function compared to the general mind set of card users. The smooth stability and function of this GPU more than makes up for the falts of the touchy so-called faster cards...It just WORKS! every time -all the time.even on older systems like mine. I use it for X-Plane 12 and DCS World flight simulation. My rig is a Dell 9020 optiplex MT with an i7 4790K CPU, 32mb DDR3 RAM, 2TB ssd main and 2TB ssd storage drives., Corsair RM750X 750 watt PSU. Snoother and with better frame rates than my GTX 1080 ti........Don't believe the naysayers...!!
