Damn! Only have a 6850 1gig. Thanks for the info though. From what I've read, review wise, my card averages about 20fps less than yours. Guess I need to overclock more.
Also, if you have any questions I may be able to help with the overclocking. I use "SapphireTrix" for the GPU and use the bios to keep my CPU at turbo 3.8ghz (I have a LOCKED intel chip ). The overclock on the GPU netted me a gain of about 15fps. That's with stock voltage running at 950mhz GPU (775 stock) and 1050mhz MEM (1000 stock). GPU clock has the biggest effect.
People at the iRacing forums are recommending at least 2Gb for triple screens. My card has 3GB.
I built the system with a little overclocking in mind. I have a decent psu, an unlocked cpu with aftermarket cooling, the gpu has two fans and the case has many fans including a 200mm fan over the GPU. But I've never really done any overclocking. A step by step guide would be helpful.
That's where I'm borderline. I have read the same, that a min of 2gig is recommended even for a single monitor at 1920x1080. I can easily run my card at 1920x1080 (with a different monitor) but my usual monitor is 1600x900. I will probably not do triple until I crossfire or upgrade GPU.
Also, was earlier thinking of the 7750. Your card is bad ass! Except for pixle rate, you double everything else I have performance wise. Nice choice!
For overclocking, you are already a step ahead with the cooler, so the battle is half over. Keep in mind, I myself (if my cpu was unlocked) would only go for a mild overclock of about 4.2ghz. From what I've read, 4.2 is about the limit one would run a pc daily at. All those higher clocks you read about are only for bragging rights. More voltage is needed to reach higher clocks, which creates heat, which wears on the CPU.
Two more questions, then I can give you the steps for a mild overclock. Higher clocks, I would have to re-research, as more is involved than just the multiplier.
Q1: What cpu do you have? ivy, sandy?
Q2: What motherboard do you have? Z68, Z77? (brand also would help)
This will help me give you max temps, where to look in bios, etc...
