Will a video card help with lag spikes in World of Warcraft

Lag spikes can be caused by alot of different things and video cards are just one of them. They can also be caused by having a ton of people in the same area (like Dalaran, Org, or Stormwind or raids), or having a bad connection between WoW and your ISP (Internet service provider). Video cards can help with the lag as well as having the best internet connection you can afford.
