Here is today's Newegg Shell Shocker:
http://www.newegg.com/Special/ShellS...4-_-07252013_1 $350 Dell Core i3.
I don't know much about the i3 for much more than running the basic driver station and programming the cRIO. If you think you will be doing vision processing, this might be insufficient.
Newegg has this type of deal every day, so look back if you miss this one.
