PC build recommendations: $600 budget?

Here is my plan for a new build. I’m looking to pull the trigger by $1333 (I can stretch the budget slightly, but not by much). I don't need a GPU, power supply, cooling, or an SSD.
I am really leaning toward a Core i7 processor; does anyone know of a beastly CPU with decent integrated graphics that could carry me through gaming for a little while until I can afford a dedicated card?
I was considering either a Core i7 4790K or a 4790.
I also need a motherboard that will support a Radeon RX or even an SLI/Crossfire setup down the road.
I honestly couldn't care less about the HDD—as long as the rest of the components are high-performance, feel free to cut costs on the storage.
Just let me know if this configuration makes sense. I'm located near Austin, Texas, so I'm hoping for some cheap shipping options or perhaps something available locally. Thanks! 😁

Here’s your own dedicated thread, though this isn't actually about RAM

First off, tell me exactly which power supply you're running (full model name) and what kind of cooling setup you have?
Would you even consider overclocking? You don't really need a Core i7 just for gaming. Running four cores would just be a waste on an i7 and a motherboard configured for SLI/CF. Besides, you'd end up playing on integrated graphics anyway...

This isn't going to work. He’s obsessed with getting an i7 or whatever, but he’s completely ignoring his power supply and hard drive.

You can actually have a decent gaming experience even with an i3, but if your hard drive is a total snail, even an i12 won't save you.

Look, if you want a beefy CPU, a solid GPU, and maybe some liquid cooling, you can't pull that off without a high-quality power supply. If you try to run all that gear on some ancient, cheap unit, you're basically building a grill—you'll just end up frying everything and having to buy it all over again... 😬
