Hello and welcome to the forums
The first link doesn't work,but i think its the ASUS G60.
Well GTX 260M performs better than a GTS 360M in games,but G60 has a faster CPU.
So if its strictly for gaming,then go for G72 because of having a better VGA.
Another good alternative would be ASUS G73(check from bestbuy)which costs $1200 and has an i7 CPU + 5870M which performs significantly better than those 2 in games
