any of those cards would work great with the games that you already play. As far as crysis goes, the 1gb card would probably do you a lot of good. I just am not sure if it would be better for you to have 1gb of ddr3 or 512mb of ddr4. while ddr4 is faster, I would imagine that you would be better off with double the memory. i could be wrong on that, but someone will come and correct me if I am.
