Samsung RV510 or Dell Inspiron M5030 ?? Either of them any good ?

Decided to buy a laptop but not too sure what to look for, there's sooo many choices. It's mainly for college work but in my free time I have a couple of EA games I might play on it, I am happy to run them on low settings, but wondered if either laptops wud run them at all, as the games are high demanding ?? The Samsung has great memory however not so good graphics, where as the Dell has less memory but an ATI graphics ?? I am also not too sure if to trust the dell as I have heard dell's are not that great.
