你的LCD 大 所以至少我覺得 最少要7600GS 以上比較好..
然後..介面又是AGP的....以後再換 也是會以PCIE為考量了
要不要考慮做大昇級後 就不再動它了 撐到整台必須換掉..
考慮 X1950..如何~~應該是沒有破7000...

至於1080I 其實有分二種..
1080i和1080P格式，但1080i是隔行掃描，而1080P格式是逐行掃描.

給你看段說明~你可能更清楚一些:

Extracted from "HDTV (High Definition TV) Definition / What is HDTV?"

"Interlaced or Progressive Scan (i or p)
The first HDTV sets were available in 720p and 1080i, but not the top 1080p format. The number refers to the lines of resolution, and the letter means the signal is interlaced (i) or progressive scan (p). Many HDTV sets support only 720p, which many think preferable to 1080i for action movies and sports; however, the difference is often subjective. HDTV sets that support 1080p, which began to appear in 2005, ended the argument.

HDTVs upconvert DVD, cable and satellite broadcasts that are transmitted at the standard 480i resolution to the HD resolutions of 720p, 1080i or 1080p, whichever is the maximum resolution the set supports. HDTVs fill in the missing lines using sophisticated algorithms. HDTVs that only support 720p must also accept 1080 lines and scale them down to 720."
