Hello,

I purchased the Ivy Bridge i5 3570k and a Sabertooth Z77 TUF MoBo. I have received them already and have them configured, but I noticed that I had purchased a gtx 580 pci-e 2.0 GPU. Will I run into compatibility issues?

Since I am using the new Ivy Bridge processor, do I have to use a PCI-e 3.0 Card?

Please let me know as I would like to cancel my order if I cant use it.

Thanks

I prefer to go with a Nvidia Card but everything has been sold out on Newegg for quite some time. I also live in Canada fyi. I have it set to auto notify when they are in stock, but as soon as I get notified, by the time I log on, they are all sold out again..really frustrating.
 
Depends on which 7970 you purchase, also depends on which cooler! Drivers aren't bad unless you are a total retard at installing them! LOL Anyways, driver problems atm usually occur during crossfire. Which you probably aren't going to do until a year or few months from now.

not sure. nVidia has been releasing cards in a hodge podge order .

though i was off topic the 670 is to be relesed in 5 days but i figured OP is waiting anyhow. plus i think the 580s are not going to be manufactured anymore(?)

Nobody has actually answered your question yet. The 580 will work and is backwards compatible but, IT DOES NOT SUPPORT PCIe 3.0. The 580 will ONLY run in PCIe 2.0.

In order to get "full" or "true" PCIe 3.0 everything in the chain must all support PCIe 3 or, it will only run as fast as the weakest link in that chain i.e. mobo, chipsets, CPU, GPU etc.

first post.

but good looking out. :)
 


amuffin and I both answered that with our first two replies in the thread (not about the 580 only being PCIe 2.0 (the OP knows that anyway), but the fact that PCIe 3.0 is backwards compatible and that he has no reason to worry)...

OP, putting a 2.0 card in a 3.0 capable system is totally fine. No performance loss or gain either way.

Ah, I wasn't trying to start any sort of argument, I was simply trying to let the OPer know that the 580 will not support PCIe 3.0 even with an Ivy Bridge CPU. In order for the GPU to work in PCIe 3 it must support it - nobody ever mentioned any of that.

^ PCIe 3.0 certainly does have benefits with software that takes advantage of it like Adobe CS, which I use for the work that I do. Not everybody is a gamer.

Even though I have no experience with that myself, I've seen other people say the same thing, so I assume you're right. But even then, it can't be more than a few percentage points of a difference. GPGPU usage is a completely different animal than gaming, I get that, but with current 3.0 GPU's , I can't see the difference being enough to be a deal breaker.
