I haven't heard them personally, but I believe the general consensus is that they're way better than most sony cans, esp the one you mentioned. Also for gaming the DT770 or A900 seem to be the most recommended ones. I tried the DT770, and they were great for positioning and explosions, the boom factor, but got rid of them. I found that I didn't like closed cans too much, I've been meaniing to try the 590's. They've been given a lot of thumbs up for being one of the most comfortable cans out there. Newegg.com has them for I think 160'ish plus shipping. You can always get them from them and return if you don't like them, but I believe they charge a restocking fee.
