thanks Wes,
sure looks like an Ati mnfctrd card, and the disk came with those latest drivers on it.
I like the Ctrl + middle mouse button zoom tip... hadn't noticed you could do that - very handy for zooming using the Wacom Cintiq tablet.
Can't say I notice any difference between the FX1500 and the V3400 apart from a feeling that the display looks 'nicer' on the V3400. 2D line redraws in non-Revit cad are definitely a wee bit snappier on the FX1500 but within Revit no difference - although, and it may be wishful thinking again, the Ati V3400 somehow feels more 'solid'... not sure why. Time will tell.
