"The ATI Radeon HD 5450 graphics card that was launched last week brought full DirectX 11 support, ATI Eyefinity multi-display technology and ATI Stream technology support for ~$49. That is a hard combination to beat for the price, but the Radeon HD 5450 graphics card wasn't that great in gaming and some have said that it is too weak in compute performance. The ATI Radeon HD 5570 that was introduced today has four times the compute performance on paper and we were able to see nearly a two times performance difference in real world game testing. Not a bad increase for just an extra $30, but gamers will be hard pressed to go with anything less than a Radeon HD 5670 as it does much better across the board when it comes to gaming..."
