Hell yes you can play games on that!
Radeon mobility 9700 with 128mb dedicated memory.. I've seen a similar model in real life... they play games very nicely
That is an excellent specced machine for the money and should handle about anything you throw at it. However, I would imagine that won't be that light in weight.
1024*768 is no longer the de-facto standard for laptop screens Chris. Not for the last 6-12 months. Most laptops optimal resolution is 1280*1024
What you should consider is this. The price is great for what you get. However... what about the warranty? What does it cover?
If it dies in 6 months.. will ALDI simply take it away and take an age to refund you? Or will they send it away and you wait 2 months for a fix??
While the price is keen, the support may be lacking when you need it most. My ACER came with three years two day turnaround (including accidental damage).
