Before I actually read the thread, I thought you meant Tech sororities like... um, I don't know, an engineering sorority. There is one of those, isn't there? ANYWAY...
I'm not much help, considering I know nothing about Texas Tech. But let me try. Here's the Panhellenic page, which has links to all the sorority homepages. And it also shows the crests of every org., which is really neat to look at.

Wow! You're lucky, there are ELEVEN groups to choose from, and they are all strong nationally. You also might want to check out each org's national homepage (link from their chapter site or type in

And the Rush threads on this board are a WONDERFUL source of information, with plenty of lovely tips and lots of encouragement.
That's as much as I can do... I'm trying to recall if there's anyone from Texas Tech on these boards that would be more useful.
AHHH sorry I keep editing... I'm also going to leave the link to the student orgs, because the chapter webpages aren't all listed on the link above.
