Summary: to begin with it was an easy install. Pieces for adapting it to a low pofile box were included. Total time to modify and install was about 15 minutes. As far as performance I wanted sharper video and the HD5450 delivers just that. I am not a gamer and that application would be the ultimate test. Sorry that is all I can say.
Summary: I got this card to replace the broken video card in my brother's PC. It had a failed fan and cooked. Ouch. With this ASUS AMD Radeon Silent series the risk of fan failure on the video card is eliminated and the system is even more quiet. For his use this card has more than enough power. He uses his computer for email, web surfing, and working with documents in word or running applications like turbo tax.
Summary: I am using these cards for Dell Optiplex GX 620 and 745 models (desktop size and small form factor). Why use this card? Low power supply consumption, quiet, 1024 DDR3, and it fits. Also, the card has VGA, DVI and HDMI connections to hook up video monitor, TV etc. Great price. Amazon prime shipping too!
