No offense but i think thats just personal experience and opinion, we are all entitled to our own opinion. Razer is one of the highest rated PC gaming companys and iv owned a Razer Naga for almost 2 years now and have had absolutely 0 problems with it.
Would he really struggle say recording or streaming some of those older games listed with a gtx 950 rcoon? I mean isnt that same level as a 760 and I know of one streamer and recorder that uses a gtx 760 and it does fine.
I think honestly depending where you got that gtx 950 see if you can get a refund, buy a gtx 970 g1 gaming prolly seeing your name. Then maybe next save for a 4790k if your still not capable of doing what you want.
