i5/i3 are Sandy Bridge/HD2000-era stuff, which is still more than enough. He doesn't game. Unless you're doing 3D stuff, the GPU is utterly irrelevant (it may be used a bit for compositing, but even old Intel stuff is more than capable of that). (I have a Sandy Bridge laptop that I use with dual monitors for all kinds of (raster and vector) graphics work no problem from the GPU; going to 8MB RAM and installing SSD would definitely be the preferred ways to speed it up.)
Your selection's great otherwise, and if the scratch and dent pricing puts it ahead of the other offerings it might be worth it even with the overkill GPU. But if it were me, I'd at least check if it's available without or if there's something comparable without at a competitor.
I don't disagree..weirdly they have like 30 of these, all identically speced and all at $405 or $459.. and atm nothing else even remotely interesting or similar. I've been watching the others who carry Lenovo refurbs, nobody ever beats their prices and nobody else gives you the one year warranty so on Lenovo I mostly just check the Outlet these days. Having pulled apart tons of Dells to find that everything has been stripped from what started as semi-standard motherboards, plus their charming habit of undersizing their power supplies even more than most...and switching the wiring standard on the main PS to MB harness so attempting to use aftermarket or standard PS fries your motherboard...and I just avoid them now.
