yet another "what memory should i buy" thread

im pretty uneducated when it comes to good memry, and was hoping you guys could help me out.

right now i am running a NF7s mobo with a 512 stick of hyperx KHX 3200 (bh-5 from what the sticky at the top says) and a pair of really cheap 256mb pc2700 that i want to replace.

do i want to find another KHX 3200 stick to replace the 2 cheap ones with or would i be fine with any brand or model as long as its made with bh-5 chips?

from what i understand the nf7 works best with bh5. if ur gonna stay with that mb id just look for another stick of some bh5,u should be ok as long as the second stick is from a good manufacturer ie corsair/mushkin kingston...
