Well most cards in general such as Video, scsi, network, modem cards need an IRQ.  Your old board allowed you to change the irq in the bios so you can Hard set it before it went to the OS.  Another term for it is PCI Steering or IRQ Steering.  You can change them to allocate to a different IRQ if you had a specific piece of hardware that you could not change the IRQ to.  Hope that helps.  
Nowadays w/ plug and pray, it makes it a little easier because the OS's a little more IRQ friendly.

You need from IRQ for your VGA card only if you use it's video input (if it has such a input).

Some OSes require an IRQ to produce video output.  
Windows 95 and later do not.
Allocating an IRQ on a PC that runs Win95 or later does no harm and does no good, except wasting an IRQ.
