Well, I just got a new EVGA GTX-780Ti sc and decided I wanted to utilize PCIe 3.0 so I got the new board. Then I decided I might as well go up to 5.0GHz because my primary joy is FSX and it likes all the GHz you can muster. That led to needing a better cooling capacity so I ordered a new water cooler system from FrozenPC to replace my Noctua NH-D14.
Then.... I thought maybe the old memory was not really up to the new build so I would update it too. So I bought the new memory before checking it out here at Tom's.
So.... that's how I got here.
Now that you mention it, should I give consideration to 1866 or better rather than sticking with 1600?
Well if there is lot of price difference I would prefer 1600Mhz and OC it to 1866 Mhz.
Go for low voltage model cause it can be overclocked better. (At similar voltage 1600Mhz 1.5V can go to 1866Mhz at 1.65V.)
