[Messer]

Recently I read a similar thread in a Bulgarian hardware forum - well, the 3850 should be better than the 1950 , though probably not by much with AA turned on. Otherwise, it should smoke the older ATI card (I'm using an 1650PRO and I've compared it to the 3650 , the HD3000 series are simply better and faster than the x1000).

Otherwise, a new mobo and either an HD3870 or HD4670, or an nVidia 9000GT all with 512mb DDR3 memory should be enough and you won't have to spend a lot.
