Dear Sir,

After browsing ASUS official P5Q Pro forum, there are something interesting.

During past 2 months, P5Q Pro seems have some trouble with HD4870 no matter which brand of HD4870.  Most people have similar system specification and no post symptom.  In the last one example (he is the only one got post) hints the issue related to memory position and NB chip's voltage.

anyone that has heard of problems feel free to add as well.

Did you get a P5Q pro over the P5Q because of crossfire?

if so, you shouldn't have... Crossfire scales horribly on P45 chipsets

Wow, interesting...

Might have to rethink my build...

mmm im having problems with mine... but im trying to work out whether its just a faulty card... or card/motherboard combination or waht... because my card didnt work in a friends computer who doesnt have a P5Q.... so im confused.

Get a X38 / X48 chipset motherboard if you plan on Crossfire...

Personally I have allways been a 1 card guy since it's allmost allways cheaper to just buy 1 awesome card instead of one good card and another one years later

Plus 2x cards are not 2x the performance....

And two cards could require a better PSU aswell

Max has a 4870 and a P5Q Pro with Crossfire and has no problems

fix'd

But.. although the bandwidth is good on the P45, the real performance does get a noticable hit... tweaktown tried it...

massive drop in min fps as well... 20fps on x48 and 12 on the p45...

do you have any results on the X38?

x38=x48.... only difference is BIOS... And not even that cuz I flashed my Asus P5E X38 to P5E Deluxe X48

...do tell!  the boards are mostly similar then?  and i thought rampage formula was extreme .  guess that's so early 2008, right?

for some reason i couldnt see the crysis benchies... but from what i saw... there was very little difference exept in WIC on full settings... which leads me to beleive its more of about how the game is optimized rather than the P45 performing drastically worse...

but i could be wrong.

all of the games in that article showed very significant differences in performance between X48 and P45.  and the image doesn't work for me too.

and yet there was extremely little difference in 3dmark06 and vantage...
EDIT: and cinebench

3dmark06 scores hardly tells anything... hell a HD 2900XT CF scores higher than 8800GTX SLi....

which one u game more... cinebench and vantage or all games?

and there are very significant differences especially in minimum fps in pretty much every GAME. Dropping minimum fps about 40% just because you have P45 instead of X38/X48 clearly justifies the price difference if you are even thinking about buying CF in future.

true. but this test was done with 4850's.... i doubt in any game u could visually notice the difference between 2 4870's on P45 or 2 4870's on X48. im sure u would notice the difference in benchmarks/testing... but either way u still have a decent amount of graphics power on your hands... really it comes down to how much people are willing to spend.

I can notice such differences in minimum fps. going from 12 to 20 is not a small difference when it is in minimum fps.

the performance difference x38/x48 gives actually makes especially the x38 pretty good bang for buck. the results with hd 4870 in cf would show differences in similar scale. jsut a tad higher fps overall along the benchies.

my point: if u are spending reasonable amount of money in CF already, why would you drop performance so much just for that little extra x38 costs?

Yes i know 12 and 20 is noticable but thats a 4850 which i stated not a 4870. someone whos buys a P45 is not really thinking of CF in the near future... rather a possible upgrade later on... leaving the possiblility for CF open while not pay more since 90% of the time u would end up just using a single card solution.

Bottom line in my opinion: X48 is for people who KNOW they are most likely going to use CF. P45 is for the people who might want to, possibly some time in the future but really arnt sure... and dont want to spend the money
