PC or Laptop? CompSci

I'm going to be starting CompSci next year, but have a pretty out-dated PC/Laptop.

My pc isn't fast enough and compiles program's really slowly. I've done some game development and have realised that my PC/laptop can't handle anything.

So, since I'm starting CompSci next year I'm going to buy a new pc or laptop. Which should I buy?

PC:

More power than a laptop, at a cheaper price.

Easily customisable.

Doesn't overheat.

Laptop:

The opposite.


Do I have to have a laptop for CompSci? I was thinking of buying a decent Pc for first year uni and MacBook Pro/air for year 2... I'll only use the macbook for basic stuff(that's why I chose a macbook lol, they're crap).

Edit: My current budget is £700-800 MAX = $1155 - $1318

Nice bating with the "lulz macs r crap" (if you really think that, save yourself what is clearly going to be a huge pain and just don't get one.)

It's convenient to have a laptop to take to lectures and tutorials, especially more practical ones. If you really want customisable, get anything other than an ultrabook and customise to your heart's content.

The most popular setup here among CS students seems to be the lightweight laptop/ultrabook along with big monitor on your desk combination. You really don't need an immensely powerful machine, if it can solve the average Project Euler problem then you'll have no problem with the first few years of CompSci.
