I'm playing dead island using my x1600. Needless to say the graphics aren't the greatest (its a crappy graphics chip from 2005), but its fun, and even then the graphics aren't terrible. All the bugs I've seen are just funny little things rather than game changing. The only actual bug that affects you is that if you fall on something slanted you don't take fall damage, which is actually pretty damn useful. You shouldn't have any issues with durability of your weapons as long as you carry around ~two or three good ones with you and upgrade them fully. I have a high-voltage machete and a toxic cane knife, both at level 5, and I have a shock pistol at level 5. Also a great way to make money in order to afford that is just to get diamonds from that one lady if you give her champagne. Also later on certain harder zombies give you a lot more money. One time I picked up 2000 from a single strong zombie. I'm not near finishing the game yet, though.
