Well, it's about the time for me to upgrade my dad's computer. he wants it moving at a decent pace before he goes back to schoool in about a month. currently, the computer is an old gateway compie running at about 900 MHz. only thing it really needs is a mobo/processor swap and some new fans (currently has NONE). my budget is around $250 USD. i can get the fans on my own, lol, but i'm hoping someone can check out my mobo/proc ideas and confirm they will work. here's the mobo: http://www.newegg.com/app/ViewProductDesc.asp?description=13-131-478&depa=1 and here's the processor: http://www.newegg.com/app/ViewProductDesc.asp?description=19-103-377&depa=1 think these will work? can i use the stock heatsink and thermal paste that come with it? is there anything else i really need? i appreciate all help. this is all to give me the comfidence to build my own from scratch, lol, and all posts are welcomed.
