PCI Express 2.0 card in a PCI Express 1.0 slot?

[bitts]

hi,
i am buying radeon hd 6970 2Gb which is PCI Express 2.0 card and i have a PCI Express 1.0 slot on my motherboard...i know it will work because they both are backward compatible...

my question is will there be any performance loss? if yes how much will it be?

or should i think about another card?

thanks in adv..

A PCIe 1.0 x16 slot = PCIe 2.0 x8 slot. So, you'll see minimal loss in performance, like up to 3-5% max.

With a GTX 480 it was 2% performance loss. I was always wondering if a more powerful card would show more performance loss.

My cards are running at 8x both because of SLi.

Still haven't noticed lag or anything.

 

[EarthDog]

8x wont cause 'lag'.
