Normally retails for $1017, so roughly a 18% discount.
The Avengers bundle is just a regular 10600K (but called a 10600KA because of the bundle). You probably won't be able to claim the free Avengers game anymore (I think that offer expired in November), but that game sounds crap anyway.
Hilariously the Avengers Edition CPU with Marvel crap all over the box has a tiny print disclaimer of 'Game not included'. Thanks Intel, very cool.
Quick statitice shows this bunch costs $933 separately so not bad
