I have a MSI Z77 GD-65 gaming board with an i7-2600k. I recently started overclocking and messing with the BIOS and what not and I realized that my ram frequency was capped at 800mhz. The set I bought was a 4x4 GSkill 1600 mhz set. I did a little research and realized that for my mobo to get that ram speed, it needs a 22nm architecture and the sandy is 32nm. So my questions are this:
1) Would the increase in Ram speed improve performance at all? The board supports a lot more than just 1600, so OC is possible.
2) If 1 would increase performance, Should I get an i5-3570k or an i7-3770k or change both the mobo and processor and go with the Haswell variants of those two processors.
I tend to use my computer for gaming, but I like to enjoy the best general performance possible. Any advice would be appreciated.
