Hi! I have a question. My pc have a phenom 9950 x4 be, 8 Gb of ram DDR2 800Ghz, motherboard is m4n82 deluxe, and not long ago i bot an xfx r9 270x. Right now i have a big bottleneck(when cpu is at 100%, the GPU is at 50%). my motherboard supports the phenom II x6 like 1055T (90€ ebay) or 1100T(150€ on ebay) that will reduce the bottleneck. my question: In it worth updating only the CPU keeping in mined that i have ddr2? if it does, witch one of Phenom II x6 should I buy? if not, say so please! Update CPU or update Cpu, ram and motherboard.
