The only thing wrong with buying two separate 1GB sticks is your OC may suffer. Reason is since dual channel kits are "supposed" to be two identically matched sticks they will perform very similar in terms of voltage response and subtimings. If you have two random sticks one might perform better at 2.6v and the other at say 2.8v, hence your max OC would suffer. I would wait or find some place else for a dual channel kit, but that's just me. ;)
