Hi,

I've currently got a GTX 580 and am wanting to upgrade it while I still have some money to either a GTX 780 or 680 (looking at the charts there's been some huge improvements, mainly with the 780) but my motherboard only has a PCI-E 2.0 x16 slot (which my 580 is sitting in), are the 680 and 780 backwards compatible?

If so, what differences will I see?

Cheers,
Eddy

It'll work fine...plenty of people have a 680 on the PCIe 2.0 bus.

It will depend on what res you're playing at, but I doubt that you'll see a huge improvement. A 580 will still play every game going at max or near to max settings.

I know that the 580 plays everything fine at the moment, but I'm talking about the future. As I say, I want to upgrade while I still have money; when my 580 starts struggling I may be short of cash and unable to upgrade; so I'd rather do it now, I hope you understand?

So, the 680 works fine? Is it the same with the 780?

Go for it. No problem . There is not much performance drop from pci-e 3.0 to 2.0 . the performance drop is unnoticable . Dont worry.

780 works fine on PCI-e 2.0... absolute worst case scenario you'll lose like 2% performance

In five years it may matter that you have PCI-e 3.0 instead of 2.0 but right now it is irrelevant.

Thanks. You've put my mind to rest. I'll probably be going for a 780 and ebaying my 580. :)
