The mobo and CPU are significant upgrades, but can't tell you if the RAM is an improvement, based on what you've posted. Post the specs on your RAM and the G.Skill RAM (or better yet, post a link to both)
You are correct in your assessment of triple channel memory; only the i-7 supports triple channel.
One thing to take note of with RAM and i-series is not set your RAM voltage higher than 1.65v, or you'll risk damaging the CPU.
Thanks for the response T_T
I'm not real sure what my old ram is but I bought it about 2 years ago and got a pretty decent deal on it so I'm sure compared to today it's not much
