Laptop GFX card that equals or surpasses an HD6870

[KBnugz]

As the title states, I need some comparisons. I have a good computer I built a little less than a year ago, and thats the GFX card that I purchased (HD6870). I'm looking at laptops, but don't know which cards will be as good or better than the one in my desktop. I don't game a lot but once in awhile I'll play some L4D2, CSGO, GTA 4, etc...Any ideas? Thanks in advance

GTX 660m or AMD equivalent or better will meet your needs

Thanks for the equivalent, exactly what I needed to know. As for "samuel", thanks for the input. I kinda knew the 7970 was way better lol. Unfortunately, getting a laptop with that kind of power is going to be over my budget.
