I'd rather just keep it in from the time I set up water on the gtx 480 I just got. Would it be cool to just leave the card there but unplug it from the psu?
A watercooled graphics card is, indeed, a pain to install/remove.

I do not think unplugging the two PCIe power connectors from the GTX260 is 'enough'. The system will still detect it and will report with annoying error messages. So, I suggest to take these steps:-
1. In Nvidia Control Panel, choose the GTX480 as the Physx processor
2. In Windows Device Manager, disable the GTX260

I think these steps would put the GTX260 into an idling state and is probably most energy efficient (next to removing the card).

Note: do not choose "Uninstall" in Device Manager instead of "Disable" because it will be reinstalled upon the next boot. The PCI-E slot supplies enough power for the card to be detected by an operating system.

I think you have to change from 'Auto' to 'x4' (where 'Auto' is just default x1).
See the two pics below.
I see it thank you.
