hd 5870 crossfire problem

[CoMa]

Hi to all i'm new and i'm italian, so sorry for my bad english!
I see your forum it's very good with very imba preparated ppl on computers, now i need your help mates
I have this rig:
corsair tx850 watt
8 giga ram 800 5-5-5-15 elite group
phenom 2 965 c3 3812 mhz overclocked with 1.5 vcore and NB at 2400 with 2.5 volt
motherboard: asus m4a79 deluxe
casa twelve undread and noctua nu-12p like heatsink

Now i have 2 hd 5870 shappire installe, one is reference and the other is game edition, i have flashed the same bios that i have downloaded from this site, now the question is, is reference and game edition the same?
The only thing that change it's the design... but i want be sure i have done good flashed both with same bios.
My phenom 965 at 3812 ghz will bottleneck my crossfire?
It's normal when i do a game and then i do another when i start the second i see for one istant one image of the first?
how i can reduce microstuttering and flickering? sometimes i have them...
Thanks in advance for help

to answer the questions i can answer:

at 3.8GHz i think you will be bottlenecked, yes. But you will still get great performance anyway.
Yes, i too see that brief image of the last game sometimes. Most often in DirectX 10 games.
Stuttering can be caused by hundreds of things, its hard to find out whats causing it.


Also, go into the USER CP setting (scroll up near the top of the page), find "system specs" and fill out out, and change the drop down to "yes" so that we can see it.

If you're playing DIRT2, (which comes with the sapphire 5870, rite ? ) there is a patch for crossfire.
