Compatibility Check

So, I have a quick question for you all... I’m currently trying to offload an old desktop I have lying around. It doesn't have a dedicated GPU at the moment, so I've been hunting for one to get it up to speed. The CPU currently installed is an Intel Core i3-3220 2.2GHz—is that actually going to be compatible with an AMD Radeon HD 4670 512MB DDR3 PCI-E card?
While we're on the subject, which of these two should I grab:
Or would this one be a better bet: 😁

Compatibility isn't really an issue here; any processor should play nice with any graphics card.

If I were you, I'd go with this instead—it’s a much better deal:

Look, I’d jump on that one too, but I’m not looking to drop cash on a GPU before $50... especially if I have to factor in extra shipping costs on top of everything else. This current option is plenty for what I need. So, should I just pull the trigger on the Gigabyte model or go with the Sapphire one?

It looks like that Gigabyte and Sapphire listing is down now...

Yeah, I just checked and they're both wiped out—sold already. At this rate, I'm probably just going to grab this one instead: http://www.ebay.com/itm/graphics-card-listing-example>

Just make sure you've got a beefy enough power supply

Is 400W actually going to cut it?

Which power supply are we talking about exactly? I'd love to know the manufacturer and the specific model number.
