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