DDR3: As low timing as possible at as high MHz as posible. I'll try writing what is common in a list. Fast memory does effect gaming performance, going from 1600 MHz CL9 to 1866 MHz CL9 will grant you 7-10% higher fps.
1600 MHz - CL7 \
1866 MHz - CL8. }> These two have even performance
1600 MHz - CL8
1866 MHz - CL9.. \
2400 MHz - CL11. }> All even performance
2133 MHz - CL10 /
1600 MHz - CL9
1600 MHz - CL10
1333 MHz - CL9
1333 MHz - CL10
The middle ones are about same performance, both in games and in benchmark, same goes for the top 2. The 2133 + 2400 MHz only comes with slow timings and almost all the 1600 MHz CL9 memory i've tested can run well over 2000 MHz at CL11, but it did almost always only create heat not performance.
My suggestion remains Crucial Ballistix Tactical 2 x 8 GB 1600 MHz CL88 vs 16 GB Memory
= All tests show no difference in gamin performance, only Metro can make use of more memory. In other words, it's completely up to the "game engineers", when the games will gain performance from more then 8GB.4 vs 2 block of memory
= 2x8GB will increase stability and overclocking potential compaired to 4x4GBHDD:
It "only" effects loading times, since when you have a lot of memory, win7 will load all it can from the game, into your memory and after that the HDD is silent. While gaming I've several times experienced so little HDD activity that my PC shuts em all down, to save power and the games never seems to care
A 7200 RPM's hdd and then you're good.
Again i suggest the same Seagate Barracuda ST2000DM001 2 TB Edited by Waszipa - 4/1/13 at 3:47am
