I haven't personally used them, but the little I've heard has been good. They seem to require a little more juice than some DDR, but there's also a lifetime warranty--which is always a plus.
latelcy is good :good: haven't heard anything about them, but as Big B said if it has a lifetime warranty it is more than likely to last a while
For 1GB its very good, GSkill is VERY GOOD memory, im a regular member on an Enthusiast forum where i help out and Gskill is one of the best memories for overclocking and memory latency (timings). Thats extremely good for 1GB Dual Channel i would highly recommend that you get this!
Anything off newegg is great, and it has a warranty like big b said, go with it! Best regards, Jmengels
