Is this primarily for D3? WoW is pretty latent tolerable for the most part, or am I just really spoiled and ignorant?
Keep in mind that while you may "feel" better seeing a lower number on that ping bar, unless you are in a very unusual network environment you're unlikely to actually notice a real difference and may actually have more issues with fluctuating latency making it harder to "adapt" to.
