I am having trouble getting clarification on whether I should use GPT or MBR on my new HDD. I am formatting a new 1 TB HDD on a new system using a MB with UEFI that will be booting Win 7 Pro. I understand my HDD is not large enough to justify GPT for partition purposes, but just want to know the other, real benefits and if the these benefits justify using GPT. Any guidance will be much appreciated.
