As an owner of an i5 7500 myself, I was actually surprised at the level of performance I got running on integrated graphics. I was able to play the following games comfortably (30+ FPS) at 1080p.
Warframe (Mostly High settings)
Rocket League (High)
Skyrim (Non-SE, Medium+)
Metro 2033 (Medium)
Crysis (Medium-High, 2xAA)
I'd estimate the HD630 slots between a GT740 and GT750 in terms of performance. What's more impressive is that these games ran as well as they did (very minor graphical glitches, no stutters) without even having an official driver from Intel yet. I imagine performance will improve once they release it. Skyrim SE has a texture issue that Intel is currently working on (a beta driver available on their site for their earlier iGPUs mentions it specifically).
Another thing, I recommend disabling some of the distracting eye-candy (Motion Blur, Depth of Field, Ambient Occlusion, etc.). Medium settings may not sound super ritzy but they look fine to me personally. At this point it's safe to say that Intel's integrated graphics are starting to become a serious choice for someone who may not be looking to game professionally or to play the latest AAA games and newest releases on launch day, but still wants to play a decent amount.
