Should I get this laptop?

[NotStan]

Basically I am kinda cheap, althogh I have abit of money to spend, I've decided to settle for a budget laptop - seeing as my current one is a piece of crap, what I wonder is - should I purchase this laptop if I intend to play games like Counter Strike Source, Team Fortress 2, Left 4 dead 2, so pretty much games that were mostly released before 2009/2010. Otherwise, would it struggle with the load?

This is the laptop;

As it stands I'll be getting it for £250 with the current running discount, which is like, OKAY-ish in terms of laptop prices in the UK.

Also what I am dubious about is the maker - Compaq, never had anything by them, so a bit weary.

Also - would I lag on minecraft? As that was my final pushing point today after being unable to play with a friend earlier on.
