Im just wondering because im deciding on whether to buy an I series or w8 for bulldozer, but is there a reason to purchase a 2600k over the 2500k? i do gaming and video encoding/converting. I have a hd 6850, and im wondering if there will be a noticable difference when converting a movie file from 1080p mkv ( or some format) to another 1080 (format that my xbox can read) right now i have an amd 640 and it takes 5+ hours for a good quality conversion. I wont be using quicksync because i have a pci card. will there be a big difference between conversion times from the i7 compared to I5?
