look at the pci paragraph. it only supports 8x!. but DO NOT WORRY! there really isn't that much of a difference in performance. maybe 5-7%. there is an article floating around that showed the difference in speeds, ill try to find it.
Thanks a lot.. i knew that x8 is not that much slower, but again i heard that x8 runs at 2gb/s and x16 4b/s..
i don't know.. i might be wrong.. but next week i am getting new motherboard and 4870..
can you tell me any good mobo?
What kinda annoyes me is that I have a Gigabyte P35 DQ6 and it says on the box that it has 2 PCI-E X16 slots optimized spefically for crossfire, except once you read the fine print you find out that those "2 X16 slots" are actually 1 X16 and 1 X4 slot... How can you label something as having 2 X16 slots when 1 is 16 and the other is 4..... It seems like pretty basic english to me... Apparently when in crossfire mode both slots run at PCI-E X8 which, for these new cards isn't enough bandwidth to allow for 100% performance. (unless I am mistaken)
Ok thanks Orbital. I was feeling that the 5-7% posted above would kinda be enough of a dip to be noticable but according to the link posted it really isn't.
Also, I have a lot of ram so I would think that would help buffer from any issues, as well as having a lot of ram on the video cards themselves.
This is all good info to know if I ever do decide to go crossfire.
I guess the only thing that crossed my mind now is, with the 4870's, and soon the 4870X2s that'll end up in systems crossfired, how is the northbridges in todays systems handling all data being shoveled at it from so many sources. The ammount of data that a motherboard has to content with just keeps skyrocketing upwards faster and faster. I know the FSB speeds have gone up but it doesn't FEEL like its keeping up with the ammount of data we're sending at it.
