Bottle neck when doing what ? Comparing a diamond stealth with an ordinary
generic VGA card there is a vast difference in how long it takes to scroll
a window or redraw a complex image. If these jobs are running in memory, a
decent video card is well worth it.

That will be an issue for sustained reads. If the drive have cache on though,
small writes will procede at the interface speed so a quicker interface is
still better.
