Prices have certainly rose in Dallas, but not to the same extent, probably because Dallas is a larger city and can absorb the growth better.

From wiki:

Dallas

2000 1,188,580 18.0%

2010 1,197,816 0.8%

2015 1,300,092 8.5%

Austin

2000 656,562 41.0%

2010 790,390 20.4%

2015 931,830 17.9%

That's pretty substantial growth. DFW experienced similar growth in the 90s and it has taken 20 years of building for infrastructure to catch up.

Edit:

Just as a comparison, here's Seattle:

2000 563,374 9.1%

2010 608,660 8.0%

2015 684,451 12.5%
