Difference in 5850 2.1 or 2.0 pci express

Im using a MSI 890GX with 1055t x6 and i plan to overclock

Was ordering this XFX 5850 but noticed it is PCI Express 2.0 so i cancelled the order

I noticed they have the same one but pci express 2.1 for $10 more

Is there a difference in here , future proof etc ? or should i get the 2.1
Will it be a problem when pci express 3 comes out ?

    In place of either card, I highly recommend this one. Since you are an overclocker, this one is able to reach extreme speeds, over a 25% overclock from a reference HD5850. This allows it to surpass an HD5870.

    But there is no difference between the PCI-E 2.0 and 2.1 cards. Either one will work fine.
  2. there this thing called...Wikipedia....and it knows all.......

    "PCI Express 2.1 supports a large proportion of the management, support, and troubleshooting systems planned to be fully implemented in PCI Express 3.0. However, the speed is the same as PCI Express 2.0."

  3. thanks shadow, i just went ahead and ordered the 2.0 xfx one to save some money i probably wont get as good as an overclock as one you linked, but the few mhz difference dont think it will make a difference in games any time soon.
    yes ct thanks i saw that generic answer already but i wanted it explained more clearly
