You're one of those people that swears they notice the difference between 61FPS and 62FPS too dale.
The fact is, run a freakin benchmark test, using sandra memory test at 2-2-2-5 and 3-3-3-8 and you will see MINIMAL, performance difference. Since your Intel does like 5900mb/sec bandwidth I bet you'd get 5880mb/sec with 3-3-3-8 instead of 2-2-2-5.
For clarity, the Cas latency and Cycle time (the first and last number) have no effect on bandwidth but rather stability. The ras to cas and ras precharge effect bandwidth but not a whole hell of a lot.
If you aren't going to OC you don't need high performance RAM. That 20 extra mb/sec isn't worth the extra $100+ dollars you could wind up paying.
I've dealt with RAM latencies and overclocking a lot more than you have so I know what I'm talking here.
You simply disagree with damn near every post I ever put up
