You can enable a tooltip that shows info about user/author when you rollover/click on related avatar.
Let’s speak clearly: if you are loooking for a plugin that enables the standard Gravatar hovercards, this is not the plugin right for you. Please look for another one.
When you rollover/click on an avatar (e.g. of a comment author), a tooltip popups and shows:
<ul>
<li>some additional links if the author is a registered user: e.g. to user post archive, to user external website, to user blog (if multisite)</li>
<li>some info from Gravatar if author is registered to that service: e.g. location, “about me” description, websites, other account pages (facebook, twitter….)</li>
</ul>
In plugin settings you can set up the javascript and css main options.
The plugin comes with some filter hooks, so you can customise the tooltip content at all.
The plugin uses <a href="http://craigsworks.com/projects/qtip2/" rel="nofollow ugc">qTip plugin for jQuery</a>.

Tipso is a simple WordPress tooltip plugin that displays a responsive, animated, fully customizable tooltip when the visitor hovers over the matched element.
<h3>Usage</h3>
The plugin adds a button in the editor. On click it opens a modal window where you can enter the tooltip content. It generates a shortcode and inserts it in the editor.
<blockquote>
The shortcode 
 [tipso tip=”Tooltip content”]Hover me[/tipso]
</blockquote>
You can also manually add the shortcode in the editor, or you can assing the tooltip functionality to any element simply by adding a class tipso and for the content add a data-tipso=”Tooltip content”
For making changes to the default tooltip options (background color, content color etc.) go to “Settings/Tipso Settings”
