I have plans to upgrade to an ATI X1900XT or XTX graphics card in the following weeks, and I've just ordered a Samsung 215TW 21" Widescreen monitor, that supports 1680x1050. I was now wondering about what is the maximum DVI resolution and frequency on a X1900XT card. I've read somewhere that these cards will be limited to "just" 1600x1200@60Hz, is this true?
