Hello and welcome to the forums mate
Well with that budget,its very hard to find a good gaming laptop, the one that u have choosed has a low-end card, i recommend u minimum 8600MGT or HD 3650 if u want to game
Also i agree with Cjl,if u can rise your budget a bit,u can get the best price/performance notebook in the market which is GATEWAY P6860FX . It has a 8800MGTS GPU which performs ver well.
BTW, Cjl your link doesn't work
