I haven't heard people talk about Kingston in years as being good stuff. The hot stuff now is G.Skill and Corsair. Personally if I was to get some new memory now I'd get the Corsair PC8500 2x1gb Dominators w/fan for $19.99 after rebate. I know that was really good stuff a while back but that price is hard to pass up now. Of course there is a $40 rebate or so.

If you don't want the rebate spend a few dollars more and get the $34 G.Skill PC8500. The PC6400 G.Skill is probably the best selling stuff out now.
