My computer has a built-in graphics card and had purchased a XFX HD6750 graphics card from Best Buy hoping to use dual displays for stock trading and occasional computer gaming. I had learned three things from this experience. 1) Most computer motherboards will disable the built-in graphics upon inserting a graphics card into the PCI-e slot, so you better be sure to get a graphics card with multiple monitor support such as the Gigabyte HD6850. 2) The number one complaint about the XFX series graphics cards from my experience and what I read here on Amazon are the noisy cooling fans. Needless to say I returned the XFX HD6750 to Best Buy and it also didn't help that I could have bought a better card for the same price. I purchased the Gigabyte HD6850 from Amazon. 3) Don't go to Best Buy if you want a good selection of the latest and greatest graphics cards at a decent price. Amazon is your best bet and the Gigabyte HD6850 is the best you will find in its class.(HD6850 Review begins here)Now for my review of the Gigabyte HD6850 card while adding new content and glossing over what has already been said. This card is designed really well with a lot of ingenuity and quality built in, coming from an engineer's viewpoint. Without going into too much detail, you are definitely getting quality and great engineering for your money with this card that's made by a motherboard manufacturer compared to other cards because of the use of 2 ounce copper board layer, unique Windforce cooling technology, and the best electronic components available such as the use of all solid capacitors, tier 1 memory, and the fastest switching MOSFETs available that all contributes to this cards performance. One problem that I foresee happening with this card is that the metal fins incorporated in the Windforce cooling can collect dust and debris in between which can cause blockage leading to the overheating of the GPU, so I recommend cleaning the fins out occasionally for efficient cooling.One major note to those considering this card is that it is 9 inches long and 3 7/8 inches wide (not including the part of the board with the PCI-e teeth for insertion) so you need to make sure your case has the room to fit it. Take a measurement from the rear of the computer where the board brackets are secured out towards the front of the computer and make sure no part of the case or motherboard will interfere with installation. The card also uses two mounting bracket slots. I did not know the exact length when I bought the card and it was blocked by my motherboard's SATA connections upon insertion into the PCI-e slot. It took me a few attempts before I found a solution. Lucky for me I had SATA data cables that are right angled at one end so I switched the cable around making use of the right angle, but I gave up a SATA slot by doing so. I highly doubt I will need the SATA slot and it was well worth being able to use the graphics card.Some other things to note that are probably already mentioned... the card was designed to be overclocked and comes that way from the factory. This means you can get more performance out of this card and yet it runs cool. The dual fans are quiet and after a day of running dual monitors the GPU temperature stays at 52 degrees C with the fan speed at about 48% using all factory default settings. I have not tried connecting three monitors yet. The card takes only one PCI-e power connection from the case power supply, not two as with the newest cards, but an adapter is included in the box with the graphics card that connects to two 4-pin drive power connectors from the case power supply if you don't have a PCI-e power connection. The box also comes with an analog DVI to VGA adapter. No crossfire cable is included. Crossfire is a feature of this card that allows you to add additional crossfire enabled graphic cards working in conjunction to boost your graphics processing capability for more extreme graphic performance. The card comes with a 3 year warranty not like the lifetime warranty of some others. If you are a serious gamer, you might buy another card after 2 years anyway.When it came to connecting two monitors, I found that the HDMI output did not scale correctly on my monitors that are set to auto scale and would have probably needed to manually adjust the scaling. I recommend connecting the monitors to the DVI-I and DVI-D ports on the card for a hassle free installation unless you need picture and sound going to your monitor, then you may need to manually adjust the picture scale whether it is a monitor or TV. Read my update below if connecting a third monitor.I will leave it to someone else to provide any graphics performance index measurements. You can find them on the internet, just Google the words 'gigabyte hd6850 performance.' However, I can say that I can now run graphics at the highest settings smoothly for graphic intense games and see amazing detail that I never knew existed!I am very pleased with this card and highly recommend it. You will definitely get your monies worth for the high performance and quality of this card compared to other higher priced cards. I will definitely consider Gigabyte graphics cards again in the future if they keep building quality and performance for a decent price.Update: If you are looking to do some serious overclocking... as far as my research goes, the factory overclocked cards like this one and ones made by ASUS are limited in that area because there are no graphic card applications like Catalyst, Afterburner, and Trixx that support flexible voltage adjustments for the new voltage regulator chip on this card that is necessary to push the card further. I would not be surprised that the new voltage regulator chip is supported in the future however. Already the latest version of Catalyst software will overclock this card to 985Mhz.Update: Its been several weeks and this video card has been a solid performer. I am now using three 22" monitors without any problems. The GPU temperature remains between 51C and 54C at 50% fan speed throughout the day. If you are considering using three monitors and your third monitor doesn't have a Display Port, be sure to use an ATI certified ACTIVE DP adapter such as Accell, otherwise you risk the third monitor not displaying. Also it has to say it is ATI certified, otherwise don't buy it. The one I am using is an Accell B087B-005B UltraAV DisplayPort to DVI-D Single-Link Active Adapter. Make sure this adapter has firmware 0x95 if you buy it because a major display bug was fixed. If you buy this adapter from Amazon, most likely it will have the latest 0x95 firmware. So far the setup has worked really really well! No complaints. 2-07-12(Check out the pictures I have included in Amazon's product description).
