yeah go for 7 – xp is old-school now, still runs ok, but 7 would be more suited to a high-end system.
It’s good fun building your own, but as daft says a small mistake can cost you dearly. If you wanna do that do lots of reading, otherwise just use one of the hundreds of online shops – Google ‘Custom PC’ and you’ll get loads – the sites usually have configurators so you can choose your own components. You won’t end up spending much more to have someone build you one. Shop around though, check reviews etc etc.
