So several years ago I upgraded my integrated graphics with a PCI (mother board does not accept PCIe) card on this XP Pent4 desktop. So I've upgraded from a 19" LCD to a 20" wide screen. The card I have now does not have a DVI port. I don't game but am wondering if I should still buy a PCI card with a DVI port or I won't notice that much difference from the VGA hookup I have now? One issue I do have is that I use the "whole" screen, e.g. my resolution is greater than the default 1600x900 and on some sites there is a scrolling lag. Could a DVI connection help with that? There are several in the $40 range. Thank You!
