I have just purchased (but not yet received) a Radeon X1600PRO 256MB 128-bit GDDR2 AGP 4X/8X (GC-RX1600GA2-D3 (RoHS)). I have 2 Dell 1905FPs and want to run them side by side vertically (each one in "letter" instead of "portrait"). Does anybody know if this is possible? Also are there any negatives to doing this. I have heard that it will slow down my system significantly, is this true? Any help is greatly appreciated.
