"Upgrading to HIS 6450 Silence 2GB PCI-E x1 for servers and commercial systems, make graphcis performances enhancement and multiple displays support possible. The card is especially useful when you want to run an extra graphics card but your motherboard has only one PCI-E x16"
「對於伺服器及工業用電腦來說,升級 HIS 6450 Silence 2GB PCI-E x1 有兩大意義,一是可以加強系統圖形功能,如支援 DirectX 11 等,二則可以通過升級支持更多顯示器,這尤其適合主機板只有一根 PCI-E x16 插槽,而又想插入多片顯示卡以提供多屏功能的用家。」
