Help with upgrading my gaming PC (GPU and CPU)

[TokinGerman]

Hi and thanks in advance for your help!

I am looking to upgrade my 4yo gaming PC as it has been significantly falling behind in performance with newer games.

My current specs:
CPU: AMD Phenom II x4 945
GPU: NVIDIA GeForce GTX 460
Memory: 9GB DDR3
Display: 1920x1080
Mainboard: ASUSTeK M4A785TD-M EVO, Chipset AMD 785G and x16 PCI-Express

I don't have the biggest budget (~700€) and was hoping to get away with just upgrading my GPU and CPU. I've read that newest games get most of their performance through the GPU, and one merely needs a CPU to keep up and not bottleneck. I'm certainly no hardware pro and was hoping to get some advice here.

I've been eyeing the GTX 970 as a GPU. I'm pretty certain my current CPU would reduce it's performance significantly and have been looking into CPUs and just read the Intel Core i5-4690 would be a good choice to go with the GTX 970.

My questions: is the CPU/GPU combination good? Performance wise, is the GTX 970 a good choice or would I have to upgrade again in a year or two to keep up with newest games? I'm fairly clueless about mainboards and so far only read that it needs a x16 slot to run the GTX 970; is my mainboard otherwise sufficient or are there other things to consider?

I'm new to this forum and hardware technicalities in general, so please let me know if I posted wrong or additional information is needed! Thank you very much for your help!

Well your definitely going to have to change the motherboard since you want an Intel CPU which aren't compatible with AMD motherboards

I know that it's not in euros but the price is just under 700€. It's sort of reference of what you can get. But really, I would wait for the new NVIDIA or AMD gpus to come out this year.
