Hello guys , I'm going to buy a new PC.I'm only a school student so my budget is very very tight.So,I can get new i3 6100 with used r9 270x or used i5 2500k with new gtx 1050 ti. I've never bought used parts before so I'm really worried that it might be a broken item. I can not buy a totally new pc because if I did it wouldn't be able to play new games as my budget is low. My monitor is 720p only. So which should be able to handle new games on mixed high @ 50-60 fps ?And is buying used parts a bad idea ? They are cheap though.Both cost the same in my country.
