So my computer is getting kinda slow and my fps is always low so i've been looking getting a new computer. So i have only bought pre built computers and now i wanna try build one my self from a website like iBuyPower or CyberpowerPC. Because i havent built my own computer before i need some help like what to look at and what is good/bad.

Thanks for the help

Budget? do you need OS/monitor/peripherals? where do you live? are you using this for gaming? need more information.
