Can a GPU of PCIE3.0 fit into a MB of 2.0?

[ltolman]

I was hoping this was a FAQ but I didnt see this

Oh my; so I did some searching and I'm thinking I may have short changed myself???

First off I own this motherboard: GA-790XTA-UD4.  Okay and it says:

0.1 x PCI Express x16 slot, running at x16 (PCIEX16) (Note 3)
0.1 x PCI Express x16 slot, running at x8 (PCIEX8) (Note 3)
(The PCIEX16 and PCIEX8 slots conform to PCI Express 2.0 standard.)


And if I were to upgrade my Graphics card; one that interests me says "PCI Express 3.0"

Now someone was trying to put a newer graphics card on an older system so I guess what I'm wondering is whether or not I can use a 3.0 PCI Express Graphics card on a Motherboard that says that "Conform to PCI Express 2.0 Standard"??

Another way is saying....do you think I can put the latest Graphics card....GTX 780 in my current motherboard

Thanks

Otherwise I'm thinking I do need a Motherboard that says "PCI Express 3.0"...in which will be like me upgrading next year; then upgrading my graphics card the following year LOL

The GTX-780 is backward compatible with PCI Express 2.0 standard so it should run perfectly on you GA-790XTA-UD4

Holy cow; really? How did you figure that out?  And I heard it lowers the full capacity?

Okay for instance; hypothetically speaking if a graphics card is rated #1 with a 3D mark score of 20,000 using a non compliant does i lower the value down to like 14,000 or something

Thank you very much though

Okay for instance; hypothetically speaking if a graphics card is rated #1 with a 3D mark ....

3DMarks are all overclocker scores ... meaning absolutely nothing.
When you put a 3.0 card into a 2.0 slot this card will run to 2.0 specs hence slower than in a 3.0 slot but otherwise perfectly fine
