High-end cards and flagship cards cannot feed a graphic card company, although that’s where the glory stands. Now that AMD has unleashed their flagship cards, the HD 6990, they are now focusing back to the lower-end cards. To cater this market, AMD has just unleashed a trio of sub-$100 cards, the Radeon HD 6670, 6570, and 6450.

For such a cheap card, usually performance is not the main factor. Reaction from reviewers has been one of mild indifference. Depending on manufacturer, fan noise does appear to be an issue, possibly precluding the cards from being a viable HTPC choice. Otherwise, even the lowly, $55 6450 is a worthy upgrade over an integrated graphics chip or a two-year-old discrete card, but it can’t match the performance of NVIDIA’s GT 430, which can be had for only a few dollars more. Doesn’t sound like good news for AMD.

Due to these new cards, older 5000 series cards are getting price slash. Now purchasers can get more bang for their GPU buck by sticking with last generation cards (like the Radeon HD 5750) if they’re looking for pure gaming prowess.
