URGENT: Need help picking out PC parts!!!

Need some help picking out PC parts. I'm just looking for a CPU, motherboard, and GPU that won't break the bank $900 I don't care which processor I get, as long as I can squeeze in a decent graphics card—maybe something like a GTX 750. Must be brand new, no used junk. THANKS

Who, what, where? Where are you planning to shop, and what's the actual goal here—assuming the GPU mention means gaming?

The most critical question here—what kind of power supply are we actually dealing with?

Just list your specs—RAM, storage, PSU, whatever else you've got...

How are we supposed to know what kind of RAM or drives you're running if you're asking for motherboard recommendations without telling us?
