Price to Performance the Ultra 265K is undeniably the King here, but for almost all gamers, the 245K will suffice.

Currently the prices are higher for the lower performing Ultra 5 245k CPU. My guess is the demand is higher because young consumers just assume the Ultra 5 will be lower in price without checking. The demand raises the price higher than the Ultra 7 265k.
