I think I'll probably sit on the majority of my gaming rig until 2015 at the least.
I might get a non-reference R9 290 to replace my 7950 boost when they're available, but then again my 7950 boost is performing fine; I can max all the games I play currently. I could also do with a new monitor, my current one is over 4 years old now, maybe I might get a 1440p one, to make the R9 290 worthwhile if I do get one. Either way, I'll be spending much less on PC hardware in 2014 than 2013. ^_^
My next big upgrade will probably be 2015. Being an AMD fan, I'll see what AMD have to offer if we actually do get another FX plaform then. Failing that I suppose I could opt for Intel's X99 and Haswell-E.
