DDR2 800 @ 4-4-4-12-2T vs. DDR2 1066 @ 5-5-5-15-2T is pretty much equal in everyday performance

Now if the timings were the same, the DDR2 1066 would be a nice improvement.

Intel chipset performs better with higher bandwidth, so 1066 would be better...but doubt you`ll notice that...Still some expesive cl5 1200Mhz modules are showing great performance...

From what I've read, performance doesn't really scale until you get above 1100. The difference between 800 and 1066 is maybe a handful of percentage points.

that`s true....and 1200Mhz CL5 sticks are kicking butt...

I have tested my rig at both 800 and 1000 and there was a 20 point difference in 3Dmark06 So for the money i would not bother.

Good CL4 800 sticks will probably give you 1060 @ CL5.
Or you can get some 667 sticks and run 1060 @ CL4 like me
Of course, $55 shipped is an outrageous price.
