8GB DDR3 (dual-channel) x 6GB DDR (triple-channel)

Just a quick question that came up in my head while I was reading the chapter about RAM in my hardware book… assuming that I’m building a gaming computer for myself with an i7 CPU and x58 chipset, what would give me better overall performance… installing 4 memory modules of 2GB each and running on dual-channel mode or installing 3 memory modules of 2GB each and running on triple-channel mode?

thank you

*** 6GB DDR3

anybody?

to be honest I have 8gb ddr2 and for the price difference I’m fine with the performance. if you can’t tell a difference why spend the money.
