PCI Express 3.0 in a 3.0 x16 slot?

My GTX 650 TI has a PCI Express 3.0 slot, but the motherboard I ordered says it only have PCI Express 3.0 x16 slots and PCI Express 1 slots. Will my graphics card fit?

Yes. They're the same revision (though this doesn't matter) and the slots are 16 lanes wide. That's the widest any slot gets, and what virtually all graphics cards use.

The PCI-E revision for the graphics card slot on that motherboard is determined by the CPU you're using. If you use a Sandy Bridge CPU with that motherboard then the PCI-E Revision supported is 2.0.

In your case you're using an Ivy Bridge CPU so the motherboard's PCI-E x16 slot will operate with PCI-E Revision 3.0. The x16 means that there is a full 16 PCI Express lanes wired between the CPU and the graphics card.

The two PCI-E x1 slots on your motherboard are wired to the Intel H61 Express chipset which is limited to PCI-E Revision 2.0.
