I love Austin, but it's probably arguable that its "culture" (in the art/culture sense of the word) even approaches Houston's. "Houston is one of only five cities in the United States with permanent professional resident companies in all of the major performing arts disciplines: opera, ballet, symphony, and theater"

And Houston is cheaper than Austin, too... but I've found Austin's tech scene to be slightly up on Houston's (if only because Austin is more compact and so getting around to the nearest meetup is a bit easier... also, Austin has a much better VC scene, but Houston does have a surprisingly large tech scene, even given that Houston is probably going to become the country's third-largest city.) http://www.businessinsider.com/r-americas-city-rankings-set-...
But bdcraven is right... modern here tends to mean .NET or Java at most of the larger Fortune 100 companies based here (mostly oil and gas, medicine, and finance.)
You'll need a lot of air conditioning and maybe a swimming pool (or two) during the summer though.
