ATI video cards have been at the fore front of features with support for DirectX 10.1 and cards with DirectX 11 support coming up later this year. Their entire lineup of video chips support DirectX 10.1, while their main competitor, NVIDIA has only now begun supporting DirectX 10.1 on their graphics chips in the last couple of months.
ATI launched their HD 4870 cards in the middle of last year. The HD 4870 was replaced by the HD 4890 on the high-mainstream area of $250 in early 2009. The mainstream chip of the HD 4xxx series was called the HD 4650. The HD 4650 is a bit underpowered for todayís hottest games but makes for a good upgrade for those having Intel integrated graphics. Today Iíve got the XFX Radeon HD 465X-YAF2 video card on the review bench.
