1280x1024 一般解析度狀況下: GTX 550 Ti>HD5770>GTS 450

1920x1080 高解析度/高反鋸齒/高異相性過濾狀況下: GTX 550 Ti>HD5770>GTS 450

功耗與溫度
http://pic.xfastest.com/elvis/Review/Galaxy-550Ti/550-Power.png
功耗: GTS 450<GTX 550 Ti<=HD5770
溫度: GTX 550 Ti<GTS 450<HD5770

總結
效能方面落點應該夾在AMD的6850與5770之間，不過首版驅動的狀態距離6850稍遠一點點
遊戲方面即使在高解析度下一般特效也有還不錯的表現
溫度與功耗方面由於製程的進步，整體都壓制在非常合理的範圍內
噪音的部分由FurMark 1.9.0測試圖可見到燒機時最高轉速來到61%的2490rpm，
8cm風扇在這個轉速下噪音其實並不會太大聲
目前得知的官方定價落點在US$149
整體而論性能/功耗/溫度/噪音各方面表現都很到位，
可惜AMD目前使出跳到溺水這個大絕招(雖然BIOS頻頻出問題XD)
如果價格再更親民一些，GTX 550 Ti非常適合中階裝機的消費者
