Worth folking out for HD650's just for gaming

Ok so the story goes, I posted I wanted to upgrade my sound setup within my gaming PC a while ago. I currently have HD555's (modded to 595's) which I love the sound of, but they are falling to piece's and quite frankly becoming a health biohazard. Also SB-Z soundcard.

As I use my audio for 95% gaming you lot told me you can't go better than the K702's so I happily took your advice and got a pair.
I hated them, the soundstage was the only good thing about them everything else felt and sounded cheap. I couldn't keep them on that basis only. Plus they were insanely painful after 30min's

So here I am still looking for an upgrade, now I don't really spare any money when it comes to my PC but at the same time I don't waste it.

I'm thinking I should just upgrade to what I know and like and get the HD598's or the newer HD599 for another £20. so £219.

But am I missing out, will an upgrade of soundcard to a STX II and a set of HD650's for solely gaming be a worth while spend of £440, so double the cost of sticking with my SC and the first upgrade.

Ok thanks for all the replies guys, I have no doubt the 650's are the better headphone but for what I need I think the 599's will be the better way to go, maybe as a upgrade later down the line I will get the GSX1000 to add to it, if this will add a bit more to them?
I can't justify the £450 needed to sport the HD650. Thanks again audio geezers.
