I know that nVidia is suppose to release their 6 new XForce chips this week (and maybe they already have, I don't know), but can anyone speculate when we will see them in Macs? These new chips are suppose to completely replace the current line of GForce chips, so will we be seeing the new ones replacing the Mac line of GForce chips? ATI is also suppose to be releasing 6 new cards this month, so I wonder how long it will take for those to make it to the Mac market, as well.
