Hi, I am planning to build a new computer over this summer. But, for obvious reasons, I am a little wary of spending $800 to $1000 dollars for a computer that might not even start up because of my inexperience. My question is, would it be sensible to hold up on the video card and just use integrated graphics until I've tested that my computer does indeed work? This could save me some money if I find out that I've broken something somehow. And if I can, how would I go about doing this (like, installing the graphics card later)?
