i can sense it in the graffics and operations.
when i am running windows 7 and play a game is notorius. When i move the mouse with a drag click on desktop is notorious.
when i run for ex, call of duty black ops on xp it works perfect, on seven is laggy whatsoever the config of the graffics.
When i play pes2011, xp is perfect. On 7, it runs kinda good and suddenly it freeze and catchs up in a flashforward motion, like normal game... freeeze 1 seg flash forward, normal game.
