You call a X70 a midrange card? These cards are usually sufficient to run games on full HD and max details for approximately 3 years, maybe only high details in the last year, and then even a X80-X95 would be too outdated to use any longer because it’s not just the FLOPS that evolve in this industry!
More powerfull cards are only appropriate if you run very high resolutions or multiple screens… or to boost your e-penix if you will excuse me stooping to ad hominem.
I’m an IT guy, challenge my power, I dare you.
No seriously: Money’s for spending! If you got it - help the economy and get rid of it!
Oh by the way: If any of you think about upgrading , by the powers of two - wait till next year or at least till winter; lot’s of new tech coming this way! DDR4, Broadwell Intel iteration, next graphics card generation as usual, etc.
