I need a microphone, but which one?

Salutations from England, Logan and Wendel.

So i want to start creating youtube videos by reviewing games and posting my opinion on them. However, to do this i should really be using a microphone where viewers can actually hear me. Trouble is; I haven't the faintest clue what microphone i should get for the job. Thus, my question is: can you suggest a microphone that fits within the budget of around £70. The sound card i use is a 7.1 system with 2.5mm jacks, a standerd thing that was built into the motherboard when i bought the computer, a Dell XPS 8100. I appreiciate your time and want to thank you for bringing us professional and informal (meant in both ways) videos.

If you require any additional information i apologise for not including it.

I also want to encourage any other reads to post suggestions and thank them for it.

Get a Blue Yeti. It;s such a great mic for recording

I would recommend the Snowball over the Yeti, looks cooler, is cheaper, and there is almost no difference in sound quality. 

Look up sound comparisons of the mics that are in your price range.

I got the Sterling Audio SP50/30 Studio Condenser Microphone Pack and it works awesome. Now you'd have to get a XLR to usb converter that would add on to the price, but imo it sounds just as good as a yeti, and you get two mics.

From what I hear, a good Sterling mic is good... But make sure it sounds right if you get one. They use cheap Chinese parts that, if you got a bad part, an rma can fix.

Seconding the Snowball, mine arrived a few days ago, this is how it sounds:
