Motherboards:
Gigabyte GA-F2A68HM-DS2
Gigabyte GA-F2A68HM-H
and can I use the same components for the Gigabyte GA-F2A68HM-H, because I was planning the Gigabyte GA-F2A68HM-DS2 but it's not available in my country.
Looks like the GA-F2A68HM-HD2 has an HDMI port and a speaker header which the GA-F2A68HM-H lacks. Other than that, unless I've missed something, the specs appear to be identical.
Which one would you suggest and if you dont want to it's fine but can you suggest components for a game pc under $450?
I apologize, I had one of the part numbers wrong earlier. Literally the only difference between these two boards is that the GA-F2A68HM-DS2 has a VGA and a DVI-D port, and the GA-F2A68HM-H has a VGA and an HDMI port. For a gaming rig with a separate graphics card, this would only matter if for some reason your video card quit working, or you removed it, and you needed to use integrated graphics (assuming your processor has them.) They should both accept the same processor, RAM, video card, etc.
What country are you in, and what is your budget in the currency you would actually be purchasing the parts with (if not USD)? I don't mind trying to put a build together for you, but currency conversion and local part availability can make it tricky, especially if it's not a country and currency listed in PC Part Picker.
If the cable is for the video card, don't use an adapter. You need to use the power cables that came with the power supply unit (PSU.) If you're trying to use a PSU that you already own and it doesn't have the right connector, then you need to get a new PSU that does.
I'll be honest, this isn't going to be a very fast or powerful machine, and it's won't be able to handle recent games very well. Here's a couple of charts that show how different CPUs and GPUs compare to each other:
