Would you have been able to develop for it on a budget rig?
Of course a nicer computer always helps, but honestly, even nano and gcc on a Pi can get you pretty far. There's a huge difference between "download this free software on your existing computer" and "beg us to sell you this $2k+ machine that will ONLY work for this one task".
I would not develop software meant to run on specialized hardware like a modern gaming computer on something less powerful than the target platform. That's just asking for trouble.
