I have built over 300 computers from scratch. I am a quad-display guy and have been for the last 6 years. I have gone through every under/sad-performing Matrox card there is and most recently the always-buggy Quadro PNY NVS-450 that sorely tested my patience with 3 or 4 boots every morning just to get it to work properly. If your monitors are DVI/VGA then you will only be able to run two with the 2 included DVI adapters. The other 3 monitors will need from Newegg the Sapphire ACTIVE DisplayPort-to-VGA adapter (max 1920x1200) for $25 ea or a full ACTIVE DisplayPort-to-DVI adapter for $125 ea. I am using the $25 Sapphire units and I am in heaven. THIS card is pure joy to you quad-display geeks who have waited years for multi-display perfection to arrive... along with superfast GDDR5 memory. Win7 64 bit Media Center movies play without pause and clear as a bell even whilst you have 8 other windows open.


I was upset that I had to spend two hours researching passive versus active displayport adapters to figure out what additional hardware I had to buy to see all 4 of my monitors fire-up and work. There were no buyer feedback recommendations/critiques/hints on this page when I bought my card. Remember, you will only see all five monitors light up if all 5 are DisplayPort models. If all you have are DVI monitors then you need to buy three ACTIVE DisplayPort-to-DVI adapters for $125 ea. If your five monitors are combo DVI/VGA then you also need to buy 3 Sapphire ACTIVE DisplayPort-to-VGA adapters (max 1920x1200 each monitor) for $25 ea.

Other Thoughts:

This ATI card is a very good deal and performs in my Gigabyte EP45-UD3LR system with 4gb memory very well. I have a 2.83 Q9550 cranked up to run at 3.11 ghz. I have set my ATI card to run locked at 100 mhz in the MB bios which now eliminates all flicker. I have also added a nice VIZO VIZO-PCL-201 70mm Blue LED Propeller Dual Fan Card next to my ATI card. I am running Catalyst 10.6 but not Hydravision software as yet. My CCC manual set fan speed on the ATI card is 65%. The CCC overdrive speed is 810 mhz for the GPU clock and 1200 mhz for the memory clock as established by the auto-tune set-up. Overall, if you take my advice the set-up of this card will be a snap. ATI has indeed become the graphics card choice of 2010 for me. I will buy more of these cards for sure.
