>> Sapphire Radeon HD 5450 512MB graphics card Review
The Sapphire Radeon 5450 is a very small, low-power, silent, budget graphics card, marketed in the sub-$50 range to consumers who may be interested in something for their HTPC or the occasional foray into some light gaming. It's the baby of the 5000 series Radeon cards, and offers some great value for those people with a minimal budget.
