Won a GTX760 should I use it? (old 580 3GB)

Hey syndicate members,

I was at Gamecom in Germany this Year and won a EVGA GTX760 SC 2GB at the Microsoft booth. And now I don't know If it will make much sense to use it or to sell it. 

My setup right now:

Sabertooth P67
EVGA GTX 580 3GB
PSU 850W Gold  be quiet
(the rest is irrelevat I guess) 

Since I don't wanna spend any money on a new Motherboard I guess I'll only have the PCI 2.0 ports for a 3.0 ready card. Now to my question should I sell the 760 or put it in my rig (and sell the 580)?

I hope you guys can help me with this :)
Thank you in advance!

Best regards

it will give you a good 10fps boost if you do use it (in most cases)  http://www.anandtech.com/bench/product/767?vs=854

pcie 3 isent even in use yet not even gtx titan can fully use the limits of pci2 you whont be needing a new mobo for the video card.

+ it will run cooler than the old GTX580 and use much less power.

PCI-e 2.0 isn't even maxed with that card. The only cards that can max out PCI-e 2.0 right now are when using multiple graphics cards in SLi or Crossfire. Chuck it in your system, load up the drivers, fire away.

What kind of monitor are you using? If you are using a 2560x1440 or 2560x1600 you will get a memory benefit from the 760. Do you use anisotropic filtering? The 760 does that better than the 580. Do you use anti-aliasing on a lot of games? The 580 does that better. Here is a web site I found that goes into more detail on these. http://www.hwcompare.com/14829/geforce-gtx-580-vs-geforce-gtx-760/ In my personal opinon I would keep the 580 in that system and SAVE the 760 for a new one. They are both good cards unless you need the cash keep them both you can't go wrong ether way. 

P.S The 760 does not saturate the pci-e 2.0 slot so don't worry about that to much.

i would stick in the 760 would last you longer than the 580 will since its a new card

How much for the 580 ?

Use the 760.

Thanks Guys you were a great help. I'll use the 760 from now on and sell the 580.
I'll have two 1980x1080 Monitores hoocked up to it.

Is there anything I should know about switching the GPU?

760 is like a about a 10% upgrade i would sell what ever one will leave you with more money in your pocket.
