can gddr5 support to my motherboard

Solution
The PCI-E x16 slot on you motherboard uses PCI-E Gen. 2.0
The GeForce GTX 750 Ti uses PCI-E Gen. 3.0

So it will run on your motherboard, but you might not get the full performance out of this video card.

I can't say, maybe another member of the forum would have a better idea.

As i said "you might not get the full performance" out of that card, but maybe it will work well for you. Your asking about which video card will work best, but what ever card you use, it's your motherboard that will be the bottle-neck.
