PCI Express 2.0 x 16 Graphics card can supports PCI Express 3.0 x 16?

[princesiddiqui]

I want to buy,
motherboard: Intel® Desktop Board DH77KC & Processor: i5 2500k.

But there is some confusion, I have gts 250 1gb supports with PCI Express 2.0 x 16 graphics card connector.

But " Intel® Desktop Board DH77KC " supports PCI Express 3.0 x 16 graphics card connector.

So, will gts 250 supports PCI Express 3.0 x 16 graphics card connector or not?

and what is the difference between 2.0 or 3.0 graphics card connector?

PCI express is backwards compatible, which means that 2.0 card will work in 3.0 motherboard and vice versa.

PCI express 3.0 is newer revision of PCI express, it promises higher transfer speed while being totally backwards compatible. However, no card in the world can take that higher transfer speed yet .

So advice for you: don't worry about it. It will work.
