Could someone recommend a good, powerful laptop? Something that's basically all around powerful, but also well-suited for gaming as well. Individual PC model recommendations are welcome, but also PC specs that are powerful and suited for gaming as well.

I'm looking into buying a new computer...by current PC is Dell Inspiron 1545 ( -___-; ) and due to my "experiences" with Dell...I don't think I'll ever get anything from Dell again

So, any help in pc model and spec recommendation is greatly appreciated ^^
