I'm from India & 16 years old. I have laptop of HP G42 400 series don't know which one of it is. Maybe it is 457 TU. It has 4 GB RAM, i3 370 M 2.40 GHz which quite good for gaming but The only thing lagging is Intel HD Graphics. Is there anyway I can upgrade the gpu? & changing the whole motherboard is not the answer. Well if its not then I'm thinking about making one custom pc but I'm having trouble with deciding which motherboard to take. I can't spend more than Rs.8000 on motherboard sugestions please.
