Not sure why I have to say this so many times: multiboxing is aways limited by cpu/ram. You can easily 5box with that $130 video card (how do I know? I used a $75 card for quite a while). Shadows are retarded, so turn them off (name one video game where you were awed by the shadows). You don't need AA/AF, view distance, spell effects, water/grass on the alts, turn them off.

Unless you'll be doing a lot of instance swapping or whatever it is called with keyclone/IS, then you'll want the better video card. Or you'll be playing other games (dead space 2, black ops, rift).

Just my 2 pesos.
