is this RAM ok?

hi im looking for some stuff on san for when i buy my new rig and was gonna buy some 1Gb Corsair XMS2, DDR2 PC5400 (667), 240 Pin, Non-ECC Unbuffered, CAS 4-4-4-12 but saw this, 1Gb Micron Major, DDR2 PC2-6400 (800), 240 Pins, Non-ECC Unbuffered, CAS 5-5-5-12, its has a higher frequency but higher latency and ive never heard of the brand. what do you think??
