will my Non overcloked amd phenom II x4 955 BE (Black edition) bottleneck my new Gpu
New gpu is r9 380 4gb from Sapphire
Current gpu amd radeon hd 6570 From Sapphire

 
There will be bottleneck but it will be an improvement over your current card. Make sure you have a good enough PSU to run it. The wattage will not matter as much as the quality. In my personal opinion I would not upgrade until you upgrade the CPU and the rest of the system. Good luck :)
