Good day,
I built a system back in 2011 and my son would like to upgrade the Graphic card to play newer games. Can I install a GeForce GTX 760 PCIe 3.0X16 on the following system:

P7P55D Motherboard,
Intel core I5 760 2.8 Ghz
8Gb of DDR-1600
Seasonic 750W Gold Power supply

The Graphic card will replace a GeForce GTX 460 PCIe 2.0X16. The motherboard supports the PCIe 2.0 and I see that PCIe 3.0 is reverse compatible on some forum but would I really gain speed (fps) by doing so? Is the mother board going to void any gain I guess is my question? Can someone give me an answer and provide advise on my best way forward.

Kind regards

Vincent

you should see an increase in fps after the upgrade. not a lot, but 10-30%. the 760 can't saturate the 2.0 version of the interface so the motherboard won't void any improvements. the psu can take the added power draw too.

Yes, a PCIe 3 card is backwards compatible (will plug into and work) in a PCIe 2 x16lane. But it will only work (exchange data on the bus) at PCIe 2 speeds.
That said, any newer graphics card will still outperform an older one (the drawing and rendering work), even at the lower bus speed.
Yes, a GTX76 will yield a significant FPS increase over a GTX460 even on PCIe 2.
