Why Integrated for HTPC?

Hi Guys,

What's the benefit of using integrated graphics?
How much less noise/heat/electricity would it use? I''m not sure why I wouldn't just get a 4650 for $30 paired with the cheapest motherboard, vs the integrated 785g

Cheapest AM3 motherboard

Integrated GPU's are recommended for HTPC builds because that's all that's required to smoothly play HD content. There's no reason to get a separate card unless you're doing gaming.

The conclusion of the Tom's review sums it up pretty good.

"I can say without hesitation that if you choose the 780G/790GX/785G, GeForce 9300/9400, or Intel G45 IGPs for home-theater use, then you won't be disappointed."

Keep in mind, the HQV test suite is a subjective test that will vary from one reviewer to another. Also, the onboard video chips may improve their HQV results with subsequent driver releases over time as they mature. Both ATI and Nvidia are notorious for fixing things while breaking something else when drivers are updated. The 9400 chipset caveat proves that fact in the Tom's review with the newer driver not functioning properly.

The 785G only lost points on the jaggy reduction test. Otherwise it would have scored a 100. I've seen reviews of the 780G chipset getting full marks on this HQV test before, so I wouldn't put to much value on it in this case.

Get the integrated for now. If you find you can't stand the PQ, then opt for one of the low end HD5xxx cards expected early 2010. My guess is you'll be happy with the integrated video.
