ASUS EAH5870 CrossFire

Well from my experience as well 5870 crossfirex is

The'll get the drivers sorted out by the time the 6850 and 6870 come out.

We will also be testing how running two of these accelerators with PCI-Express 2.0 x16 (electrical x8) compares to the same on the full-bandwidth interface, to try and give you a rough idea of just how viable a pair of these accelerators are, in mid-range and high-end motherboards.

Where is this comparison of crossfired 5870's (or 5850's) @ 16x/16x vs 8x/8x?

Unless I missed something, no, that review only compares single GPU, x16 vs x8 vs x4 vs x1.

What I quoted in my first post I cannot find in this review or that one.

You're not the only one. I can't find the scaling comparison for Crossfire either.

I've been also wanting to see the results of crossfire scaling between 8x/8x vs 16x/16x. I don't suppose this will ever be tested?

Hello, i am new here..

I need info regarding 5870 cf on 32 bit system. As far as i guess... there won't be 6GB available in the review. Here my question, within the test session, how much the main memory size available for the system ?

Sorry if my english is poor..

Yeah, I was searching for that to. I have a 5770 and I was curious about perf. difference.

think about it if on average u lose 2% at x8 that would mean a lose of 4% on average in crossfire compared to to x16/x16 so i would say 4% loss is tiny loss overall when CPU or Ram will make a bigger impact then x8/x8 compared to x16/x16 example i7 in multi gpu setups compared to Phenom II or Core2Quad you wont notice the difference

i say this running 2 5850s in crossfire on a 790gx board comparing my setup to erockers who has a 4ghz phenom II compared to my 3.4ghz and a 790fx (x16/x16) to my (x8/x8) theres only a 4-5fps difference and this of course is at 1680x1050 with 8xAA so if that dosent give you a good answer nothing will

erocker even went so far to clock his 965 down to my speeds and are fps were nearly identicle so the difference is unnoticeable in terms of gaming

I cant see any difference in 5870CF setup..the performance like using single card...sometimes it give much lower frame rates..the game that i test is crysis, Devil May Cry 4, resident Evil 5, supreme Commander 2, MW1, MW2...dont know what is the problem...this is my setup..

Lg 19 inch 1280x1024
Asus Maximus II Formula
C2D E8600 (stock speed)
4x Crucial Ballistix Tracer 1Gb 1066
2x Samsung F3 1Tb
Dell OEM 5870
Power Color 5870 (Asus bios)
Seasonic 850W

All game is on 1280x1024 (highest setting AA (max) AF (max))

any suggestion/recommendation? thanx!...
