Looking for a graphics card to pair with msi 970 gaming mobo and amd fx 8320 processor. Currently have 8 fb crucial 1600 ddr3 ram. A power supply recommendation would also be appreciated as I currently have a 430w thermaltake. My existing graphics card - asus hd7770 1gb - not sending video display and there is no on board graphics to set up bios. Any help would be appreciated.
