Hello,
My house has not attic ventilation other that the 2 gable vents.

I know I need to add eave vents but would like ya'lls opinion on
ridge vents versus wind turbines.

I have heard the pros and con from friends and family about ridge
vents and wind turbines.
ie, if it is storming badly, ridge vents can let water in.
wind turbines don't last, noisy, etc .....
etc ....

I live in Arlington, Texas. If this make a difference.

Whichever you use (and I urge both) make sure you have sufficient soffit
vents. Insufficient intake vents yields two disadvantages: (1) No cooler air
gets into the attic, or (2) the "cooler" air is sucked out of the living
area through leaks around light fixtures, plumbing, staircase, etc.

There are calculations for the requisite soffit openings on the web. Find
yours. Double it. You can't have too much soffit venting.
