Please I need your help! I want to buy a new Graphics Card but I don't know if it will be compatible:
Motherboard: GigaByte GA-P55-US3L
CPU: Intel Core i5 650 @ 3.20GHz

I checked on pc-specs.com that my motherboard is compatible with the
Sapphire Radeon NITRO Rx 460 (4GB GDDR5).

But! If that's the case, I want to know If my PC can handle the next models: Radeon RX 470 Sapphire NITRO+ (4GB) or Radeon RX 480 Sapphire NITRO+ (4GB).
Or even Radeon RX 480 Sapphire NITRO+ (8GB).

Please, I'd appreciate if you guys could help me.

Kind regards.

On the Motherboard secifications, under graphics, it says "Support for Software ATI CrossFireX™ technology only".
Which ones are those?

Kind Regards.

According to this site: http://www.pcadvisor.co.uk/how-to/pc-components/how-know-if-graphics-card-is-compatible-3588810/
and other forums, the PCIe 3.0 IS backwards compatible apparently.
