I was in a similar situation as you and from what I've read over the past week is definitely get Mushkin BLACK if you have the cash. If not, Kingston vs. Corsair vs. GeIL vs. OCZ is really a crapshoot. I've read GREAT things and BAD things about all 4. Keep in mind some Canterwood/Springdale boards have problems with Winbond CH-5 chips that in the newer Kingston and Corsair memory...
