Hey,
I'm building a PC which will be used for entry - mid range gaming.
It will probably consist of this components:

Toshiba SATA3 7200 500GB
DDR3 2x4GB 1600MHz Crucial Ballistix Elite
500W Cooler Master B Series
AMD Athlon™ X4 Quad-Core 760K, 3.80GHz
ASRock FM2A88M Extreme4+
R7 260X ASUS OC 2GB GDDR5
LC Power 975W Air Wing

So here is my question...

That 1600MHz RAM is on sale right now, it's 1600MHz 1.5v 8-8-8-24. ($15 cheaper now, will be only $5 cheaper in few days)
I was wondering, if maybe I should take Crucial 1866MHz 1.5v 9-9-9-27 RAM, which is now $15 more expensive ( will be only $5 more expensive, when 1600MHz gets off the sale...)

So, which one would be faster for my rig?
And in case I get some extra money later, and I end up buying FX 6300:

Toshiba SATA3 7200 500GB
DDR3 2x4GB 1600MHz Crucial Ballistix Elite
500W Cooler Master B Series
AMD FX-6300, 3.50GHz
Asus M5A97 LE R2.0
R7 260X ASUS OC 2GB GDDR5
Cooler Master Elite 335

Will 1866MHz Ram be better here?
How would they compare. Include graphs if you can find them, please.
 
Solution
Pure performance wise near equal, the 1866 will get the nod for wider bandwidth and maybe 2-3 (or more depending on the game) FPS, also better response when multi-tasking, large data sets, Imaging, video, etc
