A gaming mouse always helps and a headset would complement it nicely. The difference in sound and performance in minimal when considering gaming headsets and regular ones, so if you like the look of a Razor headset, I would go for it.
If you're tight on money, a regular set will do the trick (I play with a gaming mouse and Apple earbuds). The gaming mouse is pretty necessary in my opinion, but the headset might not be.
Hi, I was looking into the Razer DeathAdder and other of Razer's gaming mice but what threw me off, with yours as well, is that they are not wirelessly connected and the Razer mice need a matt of sort beneath them to work. I have been looking on the xoticpc.com website and I have found some wireless mice there. I like the look of the Razer Naga and it has lots of extra buttons which would help my gaming and it is also wireless.
Yeah, I've just heard that wired mouses are generally better for gaming, accuracy and less likely to disconnect. I'm not sure how true this is, but I just took it as advice when purchasing a gaming mouse.
Alot of wireless gaming mouses have great reviews and the Naga looks like a great choice. For me it would be either the DeathAdder (my preference) or the Naga.
