pcie 2.0 or pcie 3.0

rafin2000 · Jul 6, 2014

i have an asus h81m-E along with an i5 4570. i was planning to buy and r9 270x or a gtx 760. my motherboard has a pcie 2.0 slot. and the gpus can use pcie 3.0. so is there a noticible difference in performance @1080p in terms of gaming when using a pcie 3.0 card on a pcie 2.0 slot instead of a 3.0 slot.Please clarify.
Thanks.

You will not notice the difference.

The difference between those two is way too small. Usually 5% performance drop in some games.

Impact of PCI-E Speed on Gaming Performance

Great information on Gaming Impact and it's very very little.

Yeah. I didn't see your post since I was typing when there was only 2 posts in this thread. I had to do something before I submitted my answer. Deleted my previous post.
