Is this a good pick for my new GPU?

I have researched my little butt off and everybody says this is a good card.
This is why I had to buy a new card: http://forums.techguy.org/windows-7/...ml#post8918331
My budget was $250 and my specs are:

Motherboard - Gigabyte 970A-D3
CPU - AMD FX-6100 Six-Core
RAM - 8GB
Graphics Card - AMD Radeon HD 6870 (THIS IS WHAT I AM REPLACING)
PSU - NeoECO 620c

All the connecty bit's seem to fit my computer, and it's a bunch better than my old one....
I can't see any reason not to buy it.....but I am somebody who likes to be 100% sure before I buy something.

So...is this a good card for my system?
