The Problem I always had, was the context menus and browsing.. AMD was fine for games, but Intel seemed to do both well.
I would get a few extra milliseconds on each context menu if the PC had been up for less than 20 mins, that I could *feel* and I would get what I will coin as "White Browser Syndrome", When the browser goes white in between clicks and on start up. This didn't happen when I had used C2D, or at least it was greatly reduced. lag on properties and OS windows too, seemed greater on AMD.

but now I can feel the gap closing*... after I read that post I went and lowered my CAS to 8 and while not dramatic, it pleased me, as I could 'feel' the desktop lag go down..typically I thought it was all about speed, but it seems the speed is useless if you can't lay it tightly down. soo if I was buying again, I would go for the lowest timings, 1333 Cas7 over 1600 cas9, I know my set is not, but y'know what I'm saying, just like Nugu said, AMD really responds to Cas over speed, at 1333 I doubt you will see much of an increase and so, maybes time to lower Cas instead of up Mhz if you were upgrading.

just some thoughts there.

*even though I am on my backup just now as my TV has an HDMI fault. I had a day living with it and plan to find out about Cas7 (I was on Cas8)

If you reached a CAS of 8 at 1600, that's actually less delay than a 7 at 1333. I don't know what you are noticing, but it's either psychological or something else is going on. You are not going to feel the difference and in fact you should already be a hair faster in timings and have extra bandwidth at 1600.

As I said, those timings are in clock pulses and the clock pulses are shorter at higher MHz.

A CAS of 7 at 1333Mhz = ~8 or 9 at 1600 = ~10 at 1866 = ~11 at 2133 = ~13 at 2400 (approximately)

sorry, I wasn't clearer..

I had been using 1533mhz OC'd, @ cas 9 or 10.
1333mhz @ 8 seems faster,

I had been up to 1553mhz @ 10 and didn't notice any difference (except in games) but the desktop as I said 'feels' livelier @ 1333 @8.
