Hello,
Want to buy a laptop mainly for extreme gaming and two areas i need clarification: all things being equal in terms of price, ram, size etc
1) i5 dual core vs AMD quad core (which is beater) eg Acer Aspire 5750G i5 dual core vs Acer Aspire 5560G AMD quad core
2) NIVIDIA GT520 1 gb vs Intel HD 3000 up to 1.2 (which is better)
