Everyone has their share of 'horror' stories. However I would go with Crucial. I am sure that maybe someone is better than Crucial but i've used them since I replaced a PC with a 700Mhz Athlon and they never give me problems, and I do overclock my PC. I would recommend just going to crucial.com and buying some memory off of there...I've heard too many problems with either of these brands listed and very few with Crucial. Crucial won't disappoint you if you choose them. Before someone goes and shares their 'horror story' with me about Crucial, I would like to reiterate that every manufacturer is going to have a 'horror story' of some kind.
