Using a PCI-E 3.0 in a 2.0 slot

post #1 of 19
Thread Starter 
How much performance do I lose? I want to get a 7850, but my mobo only has 2.0. Does it matter all that much?

No, you will not see a decrease in performance, PCI-E 3.0 isn't being fully utilized, even with high-end GPU's...

It's so miniscule if it even exists. You don't have to worry anything, it's borderline marginal error. Go for it. wink.gif

this^^ as mentioned you will not see a decrease in performance as a single high end card wont saturate PCIe 2.0.. 3.0 is really benificial for multi high end gpu's setups with high res multpile monitors smile.gif

thanks guys. Just to make sure, my cpu and everything in my sig will work? I think it's only Intel that needs a 3.0 supporting CPU.

if you are not in a hurry wait till this month end. you could see price reductions on HD 7870 and HD 7850. Nvidia GTX 660 is releasing in late june for USD 300. so if you can do wait thumb.gif

I won't even have enough money for the 7850 until July -August. How much do you think it will drop?
