My friend has a dell slim pc. I has some empty pci slots and that horrible intel integrated graphics. I told her that a videocard would give her a nice performace boost seeing rendering wouldn't come from the cpu/ram, but am I right? Would a 64-128 video card from newegg that would plug into a pci slot override the intel graphics and get faster graphic rendering (just want reassurance)? She isn't going to buy the top of the line, no gaming, but it sad when iTunes slowly renders when maximizing. Her pc isn't even that old, fairlyl fast, and I've done other upgrades to it (ram and HD).
