I'm sorry if this has been asked before, but I have not been able to find a concrete answer. Sometime this week I am putting together a new gaming PC. Ive always preferred AMD over Intel and Nvidia over ATI. Is there any reason why I should not build my system with the intent of going SLi at a later date? I've not been able to really find anyone who has had major headaches with it. Any input would be appreciated, thanks.
