What are peoples opinions on the new ascent range? I assume they are the same chips just different heatspreader. Also are the redlines suppose to clock further or just run w/ tighter timings? I'm looking at either the following kits any help would be appreciated. I basically want a kit that will do 1100MHz comfortably, maybe a tad higher.

Mushkin Redline Ascent XP2-8000 4Gb (2x2)
Mushkin Ascent XP2-8500 (2x2)
Corsair Dominator 4Gb DDR2-8500 (2x2)
