Hello!

Today I'm going out to look for a new graphics card, but there's something I'm not sure about...

One of the cards I was thinking about has PCI-E 2.1, but mine is only 2.0, so I'm not sure whether It'll be compatible with my motherboard or not...

To be honest I'm not even sure what PCI-E is...

Still, hopefully someone might be able to help me with the following picture...

If I can indeed get a PCI-E 2.1 card, please do let me know!

Thanks!

There is no compatibility problems;

What is the difference in 2.1?
PCI Express 2.1 supports a large proportion of the management, support, and troubleshooting systems planned for full implementation in PCI Express 3.0. However, the speed is the same as PCI Express 2.0. Most motherboards sold currently come with PCI Express 2.0 connectors.

So there is no speed difference...

They say that 3.0 is 2x faster than 2.0 but that is not in video performance, some tests realized on 7970 there was no change on performance...

maybe in the future they will be able to improve pci-e 3.0 components.

PCI-E 4.0 is planned to 2014/2015;
 
It is OK to put 2.1 card on 2.0 and PCI-E slot looks something like this.

Thanks everyone, though I should have searched before posting, which I did afterwards...

Anyway, thanks, and already ordered the new card!
