I agree and disagree with supafly. Definite NO to the laptop. For the desktop set up, yes, you're good to go. I am running on 4gb of 1066mhz DDR2 ram 100% fine @ 1920x1080 even before I went to SLI on a single GTX 460 768mb on Medium/High with close to 60 FPS average. So you running at a lower resolution, you should see even better frames. Benchmarks show that anything 3 or 4 cores runs it exactly the same almost, no matter the CPU clock speeds. As someone who is running basically the exact set up as you're inquiring about, minus a slightly different CPU, I say you're fine. Oh and the game even on medium settings @ 1680x1050 compared to consoles, is about 50x graphically better and smoother still. You don't wanna experience this game on console 24 player servers, but on PC with 64 player servers.

Good luck!
