Is there any real world diff between 16x16 and 16x8 CF?

Hi,
I was looking at MoBo's and if I was to have two 290's in CF would I notice any real difference between a MoBo that has 16x16 PCI and one with 16x8?
excluding benchmarks, just gaming.

Thanks

not much tbh,not 100% sure but I think its something like 5% in actual games id guess at less %

it depends also on higher res ect

16X/8X? you sure it won t be an equal 8X/8X?

Generally not much in it - slightly longer loading times and you might find some situations where a game chugs due to a lot of data being shuffled it chugs a bit more but for the most part very little difference once your loaded in.

99% of systems with sli/xfire you wont notice it. Done sli 670 on the spec in sig and an i7 930 @4.3ghz. Couldnt tell the difference in games.

Maximum PC did some benchmarks a fortnight ago testing out things like PCIe 2.0 v 3.0 and x8/x16 (among other things), quite an interesting read:

I remember when I was building a pc some time ago and wanted a mobo capable of doind sli at 16/16, I was told it's not worth the price difference. 8/8 is perfectly fine for gaming and you won't even notice any difference.
