Building a new rig and i am not sure what the best path to go is when it comes to ram.
MB: MSI 790FX-GD70 AM3 AMD 790FX
CPU: Phenom 2 x3 720 BE
Question 1: If i get ram that is at speeds of 1600 but a voltage of 1.5, will i have to increase that voltage regardless so it can operated at 1600 with its 9 cas latency?
I am aware that there is a AMD cpu limitation here on ram operating at 1600. Ware i get confused is the recommended voltage for ram on this MB is 1.5v but in MSI' tested ram support list in the 1600 overclocking table most if not all of the ram is 1.65v. Hence my question if i get 1600 ram at 1.5v CAN it operate at its stock speed and latency without adding voltage; without overcloking? Or will it auto adjust to 1333 or 1066 with a different cas latency entill i adjust the setting in the bios, hence having to overclock to get the ram to work at its stock timings?
Question 2: After reading the review on this site about cas latency and speed i was still a little confused because it did not include info on different voltage settings. If in the future i would like to overclock to a moderate or medium level would it still be ok to get a ripjaw series of ram that is 1.5 1333 but with a 7 cas latency? I know that in the beginning i would not need to overclock to achieve those timings but in the future when i start overclocking would it be better to already have ram that is manufactured at 1600 for a moderate overclock or would the 1333 be fine? Then when i really want to oc i would just buy some new stuff at 1866+? Maybe more money that way, and thats kinda my dilemma with different ram modulus offering more then one speed and latency setting would it be more economical to get a set of 1600 ram at 1.5v? The 1600 is on the tested support list but the 1333 is not. Which brings me to another dilemma why does the support list say PC11000 ddr3 1333? all the 1333 ram on newegg is PC10600,10660,and 10666?
This brings me to the dilemma of choosing a AMD build. There is only a few sets of dual channel ddr3 ram the states it was specifically made for an AMD system but the exact opposite occurs for for Intel's p55 and x58 chipset. I did find one set specifically made for AMD 790FX but it has a voltage of 1.65 and a speed of 1600 cas 8. Meaning i would have to oc out of the gate. Not i bad thing i guess. or i could just let it auto adjust to whatever timmings it use's at 1.5v.
Needles to say there should not be in the begging to much of a noticeable performance difference between 1333c7 1.5v and 1600c9 1.5v, maybe the answer is to go with OCZ with a cas of 8 despite the1.65v.
I dont know enought about ovclocking yet to understand the fundementals of voltage settings.
some advice would be greatly appreciated.

P.S on another note if i am spending 1030$CAD on a system, is AMD the way to go? I like the ability MSI has to unlock the 4th core of a 3core cpu. and i like the 16x + 16x or 4 way CFx on 8x+8x+8x+8x, not heard of for 180$ in an Intel system. You pay 350$+ for that setup on the x58 chipset, p55 is mostly limited to 16x + 4x and only a few have 3 way no 4 way. Not like to many ppl will use 4 way but still this is the only board with the 790FX Chip for that price. I have made hypothetical p55 and x58 builds in the past but i always think that you get more bang for your buck, going with the AMD system. the real world difference between a i7 and a Phenom shouldn't be that noticeable, especially important because Intel is a lot more money.
This is the first time i am going to be building a computer so people who have built a few your experience would come in handy especially if you have built both AMD and INTEL.
Again some advice would be greatly appreciated.
