Summary: This was bought to upgrade a dell dimension 740 series desktop. My son wanted a system to run Minecraft, and the one he had was horribly slow. This card worked well, and was a snap to install and setup. I used it some for displaying on a 42" LCD and found the HDMI output quite sharp (almost too sharp). The adjustments were easy with the included software, and I was very pleased with the frame rate and overall performance of the video.
Summary: I purchased this card to upgrade from Intel integrated graphics on a 2009 Gigabyte G45 motherboard. The integrated graphics were struggling with 3D games such as Gone Home, even on low settings. The HD 6450 provided only minor relief to the stuttering and low frame rates, but even still at low settings it was not an enjoyable play experience.
Summary: This card is perfect if you need something quiet and aren't expecting to play games. Video and audio (5.1 and 7.1) over HDMI work without any issues. The card idles around 40-45°c and reaches 50-55°c during use. The quality of the card seems good, and XFX offers a two year warranty. You can find the HD5450 for $10 less if you are looking to save money, but the 6450 is the better card.
Summary: I was using the 'other type' of video card, and---literally---for years, I'd been trying to solve a problem with the "Kernel Node Driver." I had sought assistance from the manufacturer support site and numerous computer help sites. I had updated and rolled-back drivers, tried a couple of Microsoft support suggestions, changed some values in the registry, and nothing helped.
