7300GT DDR3 vs 6800GS?which one is better?

The 6800GS is better than the 7300GT, simple. Have fun finding benchmarks that say otherwise.

6800GS is better card hands down.

DDR3 vs. DDR2 vs. DDR on video card isn't an issue.

6800gs definitely.

I still say 6800GS, no competition.

I've been looking for that Inno3D 7300GT for a couple months now. I haven't been able to find it on newegg, pricegrabber, froogle, or even ebay. The Inno3D one is the one to get; the GDDR3 memory is clocked at 1.4GHz, and it uses the same G73 core as the 7600 series. However, four pixel pipelines are locked, and nVidia has laser-cut the core to make sure that you can't unlock them. However, that super-fast memory makes the card very fast. Here's a review of the card that I found.

It's not that much better. It (6800GS) has 12 pixel pipelines, versus the 7300GT's 8, but the 7300GT has much higher-clocked memory (1.4GHz versus 1GHz). The 7300GT has 22.4GB/s of memory bandwidth, versus the 6800GS' 32GB/s. But if you look at the benchmarks in that review that I linked to, the 7300GT comes close to, if not better than the 6800GS>
