[This may be a dumb question] So I decided to build a low budget desktop [after failed laptop] and I am stuck on choosing a motherboard. There are motherboards with on-board video cards which has vga/DSUB or HDMI output and there are motherboards without this on-board video cards. Here is the confusing part, If I buy a motherboard without a on-board video card, how am I suppose to install video card driver for a actual/dedicated card by sticking the CD into the CD/DVD drive If I can't see anything?
All GPUs implement the standard VESA "dumb frame buffer" video standard used by the VGA driver. If Windows does not have a reference driver for your specific GPU in its install image, it will use the standard VGA driver. This applies to IGP as well.
BTW, the standard VGA driver is what gets used when you boot Windows in safe-mode.
