ok, so i have finally settled with 4GHz with my 2500k until i get a better cooler. benchmarks have all improved so the cpu isnt bottlenecking the cards, but on F1 2010 if i turn on even 2x MSAA the game freezes for anything from a second to 3-4seconds whilst playing. is there something im doing wrong or are 2xHD6850s not really that good when it comes to actual gaming?
 
Hmm temps seem good enough for gaming. You may have already answered this question before but do you have another video card you can try in place of the 6850's. I assume you've tried using just the one 6850 as well?
 
Hardware wise I doubt CF6850 will fail you in terms of speed, however your problem is most like due to:
i) probably with the games itself- have you updated the game to the latest version?
ii) driver issues for the Crossfire- one reason why so many people prefer single GPU card over multi-GPU setup like Crossfire/SLI is that it is more likely to run into driver related problem. What version driver are you using at the moment? It might worth trying a different version.
 
i have tried with CF disabled and problem persists. if i turn MSAA on it does it, if i set everything to high/ultra it does it too.
think im using 11.6 at the moment as i recently did a fresh install and just grabbed them from AMDs site.
is a steam game, so i assume it keeps it up to date for me?
my last thought was maybe its the fact they are 1GB cards, maybe its not enough?

No. the 1GB vram won't be the cause of the problem you experiencing. I'm still more leaning toward this being a game issue.

How about this? Instead of using the in game settings for AA, try using CCC, set your custom AA settings and then enable the "override application AA settings" and see if the problem still occur?

ok will give that a go. would it be worth either trying 11.7 beta, or rolling back to 11.4 or something?
BC2 was pretty good, until the snow part, thn it started to get a big laggy, but cant remember the settings i used for that.
fifa 11 is awful, completly unplayable no matter what settings i use.

If two 6850s aren't good enough for gaming then I'm finding another hobby to spend my money on.

The problem has to be the game, it is infamous for being buggy and poorly optimized, the one patch they released made it even worse. I haven't play it on pc but this is all based on time spent on the official forum, check the stickies maybe someone there can help you.

ok will have a look.
the thing is, i cant remember what settings i had it on before i swapped motherboard/cpu so i dont know whether it was an issue back then or not.
 
Sounds like you're getting paging. Brief pauses (usually a fraction of a second) tend to be indicative of insufficient VRAM (the pause being for data to be shifted from system RAM to VRAM).

Longer pauses, like the one you are getting, are more commonly HDD -> DRAM paging. But you have 8Gb so this is very unlikely.

Anyway, the first thing I would check is memory usage during gaming. Run afterburner while you're gaming, then check what the VRAM usage is. If you're just getting the odd spike or two that exceeds 1Gb, then try disabling windows aero. That should free up ~150-200Mb of VRAM.
