ASUS M3N78 Pro intergrated GPU vs my old 7900GS?

Hello everyone!

First time member here though not new to the site, and I could some edumakated opinions please.

I just went through a partial rebuild of my main comp, with the new components being:
Asus M3N78 Pro Motherboard GeForce 8300 chipset
AMD Athlon X2 6000
2gb DDR2 running Dual Channel

Problem is a new graphics card just was not in the budget right now, thus I'm still running my old GeForce 7900GS 256mb/ram PCIe. As you can guess I'm a bit behind in performance in the graphics department. I am also a bit behind these days in my knowledge of where the new GPU's are preforming vs what we had a generation or two ago.

A few years ago when I was still current on hardware specs and comparisons, I would not go near any Integrated GPU with a smelly stick. But from all the reviews I could find tonight on the GeForce 8300's mGPU, it seems on board graphics have made some nice steps forward. But I can't seem to find anything so far that I could use to get an idea of how my on board graphics would fair vs my old 7900GS 256mb/ram. I know my onboard mGPU utilizes 512mb/ram, though it is "shared" memory.

So, can anyone give me some ideas of how my onboard graphics would/might stack against the old 7900GS? I can not seem to locate any clock or memory speeds for the onboard mGPU at this time.

Also, I am still on Win XP Pro. So Hybrid SLI and DX10 are out for now.

Any info or opinions would be great, and thanks all in advance.

Thanks for the reply Cyber_jockey.

I had the feeling someone would say that. Thought I'd take a stab in the dark with it though, as the 7900GS is a bit old now and low on RAM. I just did not want to muck up a new OS install with different driver sets just to confirm my suspicions.
