No, I've put artic silver on every system I've opened, but never felt the need to unless I needed to open it up for something. The systems run fine without it, and trust me if I felt a real need I'd be all over it because I'm an overclocking, pushing it to the limit, gaming fool, not just someone trying to market something with magic water included. I game on these laptops over 10 hours a day easily and I've tested myself many systems using different cooling compounds. Years past there were huge differences, but not really these days because the cooling systems are engineered and studied for the best possible configuration within reason of mass production. We play with many liquid cooling options here locally and also using sealed oil units with the system completely submerged. The ony area it pays off is in extreme conditions of overclocking and set up which also still come with higher maintenance and risk. This leaves us back to sticking with what the engineers and manufacturer sends it out with. If you want to put AS on your CPU go for it, it should only cost you a couple $ and take about 5-10 minutes of your time... just don't expect to notice anything.
As for the RAM, unless Sager plans to change the bios, low latency RAM will not change the performance because the bios is done in a way it's intended to run @ the speed of the RAM they install. Faster ram will work, but run no faster and offer no better stability considering we rarely see a problem. If Sager plans to allow the system to be modified with lower latency and the system actually run it @ its designed speed, again, it's something you wont notice yet cost more, but it is something worth offering and we'd jump on and be up for.
The biggest performance increase in the current laptops on the market is going to be PCI-X and if they can get some 10K RPM raid drives (SATA) in them =). Otherwise, I'm not going to throw any sugar pills at you guys out of respect. But if that's what ppl really want (bragging rights), then we can check it out at least.
