Running A Phenom II 955 @3.8Ghz and just upgraded from a GTX 480 To a GTX 970 and did some test along the way. I tried to read up before hand but mixed bag of opinions some saying bad CPU bottleneck and others saying not really. Watched several video's of the Phenom II and 970 where GPU would not drop below 99% and none of the CPU cores were pinned at 90% or above so decided to give it a go.
I ran several test's both synthetics and in game fraps tests right before I put in the 970 and right After. I"ll list results in two columns one below 480 and one below 970. Hope this helps seemed to be alot of confusion when I was trying to read on it.

BF4 Bench Av FPS 3 runs GTX480- 38-38-40:: GTX970- 69-69-71
Warthunder min/max/av:480- 32/69/46:: 970- 67/107/86
All Game tests were done @1920X1200 with settings that stressed my 480 left them alone for testing to get an accurate performance increase Keep in mind also my 480 had a huge OC and the 970 is stock.
Most tests I saw right around double the performance when switching to the GTX 970 I would say if your running a gtx 480/570/660 or AMD 6970/7850/R9 270 or 270X with a Phenom II don't be afraid of this upgrade. Also searched results databases in benches that allowed me and found that this upgrade scaled the same as it does with an I7 Haswell meaning that an I7 upgrading from a 480 to a 970 sees about the same 90% to 120% increase that my Phenom II did.
Sorry for the long post but when I searched for this seemed to be alot of confusion and no real results.
