Yea you can do BF3 and Crysis easily on that laptop. i doubt ultra but its possible. And glad we could help!... If you have some questions about computers. Send me a PM. I specialize in Graphics and displays and have some experience in minor trouble shooting
I'll be glad to get your opinion at least on my next build, don't currently have one as I don't have a job & am going to college, but do you think Crysis or Crysis 2 will play on high without AA? The benchmarks say that they will... but a second opinion always helps. What about BF3 Multiplayer on high w/o AA?
