will a rx 590 work in my system?
such as: Sapphire dual-x cooling Technology. System Requirement- 500 Watt Power Supply (Suggestion) 1 x 8-pin + 1 x 6-pin (optional) AUX Power Connector Blue-ray / HD DVD playback requires Blu-ray / HD DVD drive. PCI Express 2.0 or higher version based PC is required with one X16 lane graphics slot available on the motherboard in order for the card to be compatible with
PCI express 2.0 ?
