Yo-yo. If you REALLY want to game on integrated graphics, spend the extra $30 on a 790GX/HD3300 motherboard. The HD3200 only runs at 500MHz, and while the HD3300 is the exact same architecture, it's 700MHz. That's a big difference in graphic performance. Also, many 780G/HD3200 boards only have 64MB of on-board display cache, while all 790GX/HD3300 boards I've seen have 128MB of on-board display cache. In addition, the 790GX/HD3300 will allow you to use ATI's Hybrid Tech, which means you can add an inexpensive ATI card (HD3450/3470 work) in a semi-crossfire mode later for extra performance.

It's a no-brainer. Spend the extra $30 to have much better on-board graphics processing.. you'll want it.
