I have a Q6600 with your same board and ram lol but with a not as good CPU cooler. Just wondering how come you only OC to 3ghz. I can only do 3ghz max, anything faster i need a lot of more vcore and temps go way too high (75c+ prime95 small ffts). I'm thinking if it's worth it for me to get a new hsf and trouble myself installing it just for 200-400mhz OC increase.

Will 200mhz-400mhz improve my fps a lot?
Overclocking your Q6600 from 3.0 to 3.4 won't boost your framerates by a whole lot in most games. In most cases, you'll still be bottlenecked by your single 6850, especially if your screen resolution is high (1080p or above).

I actually just upgraded to this cooler and plan to push for 3.4 over the weekend. I couldn't OC any higher because of temps going way to high so, hopefully I can get it .

As for the 6850, I tried 975 and it kept causing furmark to freeze up so I dropped it to 960 but i still got the same issue so she's sitting at 955 until I tweak the volts.

I'm not sure if those are normal but my two is crossfire never hit 70C under full load. That is a good OC on stock volts though. What does yours idle at? What are your ambients? Lot of factors that can increase your temps.

Ambient is about 21C, idle is around 40C. I tried increasing the memory clock to 1100mhz but I get errors in OCCT and there are line artifacts on my screen. Should I try increasing the voltage? Is the max safest 1.3v?

how come when I max out AA on metro the game doesn't move at all? I know it's a demanding game if i get 10fps I'd understand but mine doesn't move at all lol. also in crysis when I put the AA to 8x the fps is fast but it stutters every 5 seconds. help. my cousins 5850CF is much slower but does not stutter


edit:

don't give me "game is too demanding" and "turn down AA". I know what I'm talking about and I know this is not normal. sorry
