I'd wait on the corsair H70 (I'm using a Venomous X too, but I was thinking about a little change in 'scenery'). It's quite a hefty upgrade over it's smaller brother, the H50 (which has proven its worth for quite some time now).
^+1 I suspect it may be good as I think its the small radiator that lets the H50 down but you need to give it a week or 2 until theres some reviews out there.
