I don't know what France prices are like for computer hardware, but if it's super expensive, another alternative would be to get laptop with AMD APU, if you're into gaming.
The integrated graphics are much better than anything Intel has, and it's a lot cheaper. Anything with an A-8/A-10 processor should suit you fine. I have a 1st gen APU laptop, and it runs most things on GOG fine.
Here's one review of the latest batch of mobile APUs:
