期待測試嚕~~:)... 要CrossFire了嗎??
哈哈！應該會很強！ 原帖由 guava54 於 2007-5-22 17:21 發表
我有一點不了解，
現在市面上所謂的HDMI Output Support，都是指DVI轉HDMI接頭嗎？
沒有原生的HDMI接口嗎？（只是想要了解一下未來的趨勢會是如何）
的確有單以DVI轉HDMI的偽物
但是ATI的R600 GPU(也就是這片HD 2900XT所用的)是真的內建HDMI輸出
接上轉接頭後即會使用原生HDMI輸出
而非使用轉接頭轉換訊號 原帖由 湖太郎 於 2007-5-22 19:36 發表

連音源及影像都一體合成

NIVDIA 應該要更謹慎了R600的實力真的不錯，在預設值下，沒有TWEAK及LOD調整
在 FUTUREMARK 表現下已經讓 NVIDIA 高階卡汗顏了…
內建HDMI (顯像及音效輸出) 加上迷人的價格，2900XT 真是好物！
