PC Build + Monitor: $5k Budget

Like the headline says, I’m looking to pull together a full setup for about $750. My only real rule is that I want to buy everything from a single retailer.
It’ll be my daily driver for pretty much everything—gaming, multimedia, maybe some light Photoshop or CAD work down the line.
I’ve been reading lately that dedicated graphics cards are getting ridiculously overpriced, so I’m actually considering skipping one for now and just upgrading later when things settle down. I figure I'll get more bang for my buck with a better overall build if I go that route. Besides, I assume modern integrated graphics aren't totally useless while I wait for something decent to hit the shelves.
Thanks a lot for the help.

I wonder if it would be possible to just add a little extra to the budget so I could grab a larger monitor instead, maybe something like this

I wasn't really pulling the trigger back then, but now? Now I definitely am, mostly because my laptop finally kicked the bucket on me.
It’s the same old story, really. I just want a "real" graphics card—none of that integrated junk. I assume it’s doable to put together a decent rig without breaking the bank too badly. Though, if budget isn't an issue, I could probably push it up to $1833. The monitor is plenty big enough at 21 inches. And honestly, skip the HDD; I just need a 240GB SSD to get things moving.
