A: PC350 with Xonar Sense
B: PC360 with Xonar DG
C: Corsair Vegeance 1300 with Creative Sound Blaster X-Fi Titanium 7.1

my budget is £180 max (cant go over budget at all), and I would appreciate if people helped out with ideas too as Im not good with audio things... Thanks.

Its my first time investing into audio, 80% of the time i will be using these for gaming, mainly fps and rts. will option B be a good combination and be under budget?

I read around the subject and read that the Razer Carcharias is pretty much on par with the higher end headphone/sets. Can anyone shed some light to this? If they are really taht good, what sound card will be a good combination?
