as for sound cards they do make a hell of a difference.
also if you can find them for a low enough price I would try to find something from speedlink medusa line of headsets, I have a really old speedlink medusa 5.1 headset it's still going strong, it had separate speaker for each channel meaning the bass on it was actually unbearable at full (but then it was designed to act as force feedback as well for some reason) but the problem is they weren't cheap and you will probably struggle to find the new version for under £50. (the ones I have are long discontinued)
Let me clear something up here.
You can get good headsets, just not a very good price compared to headphones.
Let me give some examples of headphones I do think sound good. I guess you can sort of call this a semi-recommendation and I'll explain why.
The Sennheiser PC350 and the PC360. Both are great sounding headsets but the problem is the price. The PC350 is probably a HD515 and the PC360 is probably a HD518 (after listening to them). In this case, you are effectively paying 60$ for the microphone on the headphone, which to me, is a stupid thing to get. At the price of the PC360, you could have gotten Ultrasone Pro 550, Audio-Technica AD700(or A700 depending on preference), or Shure SRH-840 which are superior headphones. If you wanted to stick with Sennheiser, you could have gotten a HD555 which are all superior headphones. In the case of the PC360, you are looking at Beyerdynamic DT770, DT880, DT990 (it depends on price) or Audio-Techinica AD900. If you have heard these, it would be very very difficult justifying a PC360 over these.
The best example I can give is the Beyerdynamic MMX300. Essentially, these are Beyerdynamic DT770 32 Ohms with a mic selling for 100$+ the price of the Beyerdynamic DT770 alone. Undoubtedly, these are wonderful headsets indeed, but I feel hard to support paying 100$ for basically, a low quality mic.
In your case, why don't you get this [URL="http://www.amazon.co.uk/dp/B003JOETX8"]headphone
