Hi,
I am running now in dual display mode with my PB and a mice 17" LCD display. But I was wondering if there are any cons. or any down side of having this kind of setup. Like will games run the same or will it slow my computer down.
Any comments?
Thanks.

As far as I'm aware, the graphics card splits Video RAM equally between the two, so a 64MB graphics card will give you 32MB for each display. I assume this mean that if you are running a game on one display it will only get half of your Video RAM.

If you're running with your PB closed I would assume that the display is given 100% of the VPU and associated Vram. I would think that this would be the same as playing it on your PB (if resolution was the same). You shouldn't lose any performance unless there is something that I'm missing here... provided you keep your PB closed.
Edit: Yes i'm an idiot but it's late and I didn't read your post correctly. While using dual monitors (duh that is what you said!) you would take a performance hit in games (as stated above). Sorry for the above!

You need a big desk. For 2D there is (with a modern graphics card) no real penalty in performance.

I run dual monitors on my little 12" rev b. And I run my external monitor at 1600x1200. So I know about resolution  For 2D work, I notice extremely little to no slow downs.
While gaming in a non-full screen, I notice some slowdown (your video card is clipped in half)... so my Nvidia 5200 GO's 32 megs become 16 and 16. And that 16 megs is powering 1600x1200 gaming.... so its a little slow. But honestly not that bad.
When I want better gaming, I just run it full screen, and all 32 megs is devoted to my bigger monitor (i selected the external monitor as the master because it is capable of much higher resolution than my lcd).
I would definetly go for it. Over twice the canvas for little difference unless you are non-full screen gaming??? I think so
