Would Radeon HD 6850 work with PCI-E 1.0 X16?

[zealousalien]

Hi Team,

I am looking to use the GPU for Starcraft 2 and Diablo 3.

My computer specs is:
-Intel Dual Core E5200 O.C. @ 4.0GHZ.
-ABIT IP35 Motherboard
-4GB DDr2 Crucial Ballistix Ram
-Antec 430W Earthwatts

And I am wondering if I can purchase a Radeon HD 6850 to use with my motherboard which only supports PCI-E 1.0 X16?

Would this severely limit the GPU? Would anything else be a bottleneck as well, say like the CPU? Or would they only be tiny drawbacks?

If there are some drawbacks would purchasing a faster GPU overcome this?

Thank you for your time.

You'll be fine. I've got a 6950 running in a PCI-e 1.0 board. That PSU is a bit wimpy I think, but it's a good brand and will probably be fine. You're just going to have to be careful about adding new hardware, since you'll be close to the limit of what that PSU can do.

To confirm, there is no drop in frame rates due to my board being a pci-e 1.0? The cpu wont be affecting it either? Or is it small differences of 1fps - 2 fps?

There will be literally no difference. The only difference in PCI-e generations is available bandwidth. A 6850 does not use enough bandwidth to need PCI-e 2.0. The 6950 is very close, but it's still got enough room on 1.0.

It's like putting a card in an x8 lane. Only matters for the highest end cards.

Willard: Do you think HD 6950 Will run fine on any mother that has pcie 1.0 slot? I have asrock g965 and I wish adding that card on it but don't know in it will work. Many thanks

Yes, as long as you have a pci-e x16 slot. You may see small performance dips (1 or 2 fps), but nothing substantial. Just make sure you have a beefy enough psu.
