Sandy Bridge With a 2600K OCed ,, you will never use full 100 percent CPU power during games,,, more like 60 percent avg. Soo why upgrade CPU ? Also the difference in performance from a sandy to Ivy is slim. You will not notice a difference. What do you do on your comp that you need this. ? Video editing with Adobe Premiere, Sony Vegas or ? Or are you running a DAW with Sonar ? Even if you did these things the Sandy with 8 core after HT is enough. Your next upgrade should be when they increase the CPU count in the chip. 8 core or 12 core desktops.. gl
