GTX 480 :)
Higher performance with better driver compatibility.
Also, the HD 7850 isn't even enough for the game, while the 480 can run it easily Medium to High settings.
PS. I'm also waiting for No Man's Sky :lol:
Well then, if your BIOS shows up, you should try to reset CMOS in the settings, because your old gpu was connected to the PCI-E slot, and might have to be reset.
If you can't enter BIOS, then tell and i will try to give a different solution :)
You should try this! :)
Right after you boot, you should hear some beeps from your internal speaker, because the computer fails to detect your card.
If you have a power supply with a ON/OFF switch:
1.Place a finger on that switch.
2.After you turn on your PC when you hear the beeps immediately...
