I was referring to framerate stability as in less jerking

If as you assert there is an 8 FPS loss (which I did not see in Crysis) going crossfire, how will this affect the buyer?
If he decides to shell out another $600 for two 4870X2's do you really think that he is going to see an 8 FPS drop when compared to a pair of 4870's?
A pair of 4870X2's in crossfire can handle even crysis at high res not to mention the UD3P as mentioned above is more than $150 cheaper...
I have 3 X48 boards sitting here and yet I am using the UD3P. Why do you think that is?
I was only going by the tests they did as I have no hands on experience with the cards, a single 4870X2 is fine on the board because the board reverts to 16x with one card but if he went dual 4870X2's on the P45 I bet the framerates would be lower than 2 4870X2's on an X48 chipset. It wouldn't be that he would see a drop in framerates but if he went from P45 to X48 he could see a FPS increase.
Robilar, from what I have read on the UD3P the first slot always runs in 16x and the second slot goes to 8x so that may be why you didn't see a difference in FPS with your tests, with one card in 16x mode and one in 8x the bottleneck isn't as severe as 8x8x
No doubt the P45 overclocks better and with a single card it doesn't matter 8x or 16x but the X48 boards were made for people positive on Crossfire and if the OP is shelling out the money for the best why not go with the best Crossfire setup even if it is just a few FPS.
EDIT> and illipinoG, when you are talking about $1200 just in videocards $150 for the best performance is worth it, those 3 FPS may be the difference in beating a record for a certain game.
If you spent $5000 to break a 3DMark06 benchmark and lost by a few points due to 8x8x vs 16x16x you would be pissed
Also not all x38 and x48 boards are so expensive, the DFI X38 is $12 more than the Gigabyte P45 board and the X48 DFI board is only $60 more, $12 dollars for 3 more minimum fps is worth it to me 100%Edited by huntman21014 - 12/13/08 at 12:54pm
