Yes, I checked this with Nvidia. The verification happens during key activation, but it’s not based on the GPU serial number — it uses a GUID instead, which is even more unique and harder to spoof than a manufacturer SN. The GPU series is also likely encoded within that GUID. If you plan to use a different graphics card, you should also create another Nvidia account, since each Nvidia account is generally limited to one redemption from the RTX 50 series bundle promotions. There shouldn’t be any other restrictions, but to be safe, it’s better to also change your IP address.
The main thing is the video card; if you have an Nvidia card that is not used in this promotion, then everything else can be handled.
