Difference betyween stock 6600 and 7800 Quad graphic cards
I'm hearing that the 7800 vs. 6600 improves (reduces) rendering time. I'd like to get some kind of metric that I can use to justify or not to buy the 7800 card rather than stock. The +$350 for the 7800 isn't small change but would be a good investment if it save a bunch of render time over the weeks and months of being used. FCP is the main App in use.
Also, just how does the 7800 card help in reducing the rendering time. Is it that Apple's Core Image technology somehow offloads some of its CPU work to the card and some cards accept this while others don't ?
Thanks... Barry
