Pros: Cheap, Runs cool, Quiet, Small, Has DVI and HDMI, Only 20W
Cons: Slow in gaming
The Gigabyte HD 5450 is a seriously budget card. But to be honest, it's a case of you get what you pay for.
This card is great for Blue ray movies, and the odd game of Minecraft, but other than that it still is the lowest end card made my AMD. It won't really do anything other than what's listed above. It's still good for old games however.
I run Furmark with Xtreme Burn-in, and it only got to 50C on auto-fan settings. That is very cool for a card with such a small heatsink, and while stressing it made almost no noise either.
Because the fan is so small, even when you set it to 100% it still makes very little noise. And if you were gaming you wouldn't even hear it at all anyway, especially if you wear a headset.
Overall I think for a Budget gaming, Office use and Backup card this really is a good card. But don't expect to do any serious gaming with it. If you want to game for cheap, look at second hand high end cards.
