Pci-e 2.0 card but my MB is Pci-e x16

[NuComer]

hey guys, is it still worth it? cause right now i cant buy the card and the MB, but i was thinking about buying the card first since it can be backward compatible (according to my research) but with a performance degrade, i want to know how bad the drop is tho, does anyone have or had a gpu running this way?.

 

thx a lot :thumbs-up:

it depends what card. if it's a 5850, 5870, or a gtx295 it MIGHT be bottlenecked by PCI-E 1.0 X16 (PCI-E 2.0 X8).

 

but generally, most cards out won't be bottlenecked by the bandwidth allowed by the pci-e 1.0 specification.

You should be right, if a bottleneck occured, it would only be minor.

Get the gfx card,then upgrade your mobo down the line,simple.Although people are right when they say it wont be a problem.

What mobo are you thinking of getting? Certain ones that use a VIA chipset won't work with PCI-E 2.0 cards, but so long as you stick to Intel or AMD, you'll be just fine. But yeah, running a PCI-E 2.0 card in a 1.0 slot won't cause any huge problems, maybe a small decrease but nothing noticeable by any means.
