thanks guys thats the chart i was looking for
my current card is basically on part with intel hd 4000, and as i said its working fine i belive right now except i get the feeling hte fan is goign bad and since i have some money thats why i want to get a new card now.
funny thing my even older card aiw 1900xl is two tiers higher, for a card thats over like 6 or 7 years old with only 256megs of ram thats seems insane for it to still be so hihger on the chart. i owuld just use that if it owuld allow me to use two monitors and also didn't require the seperate power cable attached to it.
so anyways given my usage i wonder how much of an improvement i'll see on things.
i am thinking of going with the 7750
which is 10 tiers higher.
thanks guys for your help
