well i asked for people's opinions about running css at the native 1680x1050 w/ all high settings, no vsync, bilinear filtering, & no AA or 1280x800 w/ all high settings, vsync, 6x AA, & 16x AF... everyone told me to run at native settings because the picture would be much sharper and clear. imo, they were right.
honestly synthetic benchmarks don't mean much to me. i'm more practical and objective oriented. will the gpu run @ 1900x1200 with all the bells and whistles? if not, then why spend $3000 on a machine that can't run a game at the highest possible settings? i looked at the 2048x1536 numbers for the desktop 6800 ultra... which is the closest thing to wuxga. at that res, the desktop card chugged at about 37 fps in far cry w/ 4x AA & 8x AF i would expect the go6800 ultra to run about that speed or maybe slower.
short answer to if double the benchmark score is enough for me.... no, not if i want to play at the native res of the lcd.
