hey guys

I have just brought assassins creed (1) on pc.
I meet all the specs to high apart from the videocard. I have the Intel 4500hd. Now before you say anything yes I am getting a videocard ATI5770 when i've got the money.

Anyway I've looked on youtube and found people playing it on better graphcs than me whit lower specs apart from the videocard (they had the same). I can play it but on low and it's still bad.

Help.
The gma4500hd has dx10.

Thx

Also do you know where to get a cheap ATI 5770 I can get it for $280
