Which Laptop To Get

Ok, I am in the market for a new laptop. So having done some research I have a list of 6 laptops that interest me.

2. http://www.ebuyer.com/product/169936

3. http://www.ebuyer.com/product/173536#

4. http://www.ebuyer.com/product/169124#

5. http://www.ebuyer.com/product/169125

6. http://www.ebuyer.com/product/158887

Now what my main use for the laptop is college work, *maybe* some autocad course work, some gaming like counter strike, internet and watching movies.

I like all these laptops, i'm just trying to find which is the best in terms of performance.

Thanks.
