Im using a Seagate Barracuda 750GB 3.5" 7200RPM Internal Hard Drive also with a SAMSUNG 830 Series MZ-7PC128B/WW 2.5" 128GB SATA III MLC Internal Solid State Drive for bootup and some games this is a gaming pc so should i get a faster hdd?
Not really... i think you're ok but if you really want higher performance you could get a second Barracuda drive and RAID them to get twice the performance....is like SLI or Crossfire with HDDs
