Hi, I currently use two monitors and I think there would be a benefit in upgrading to 3. When I am developing in visual studio, I have the code on one screen, the debug tools on the other, and I want to have a third for the application itself to reside on.

So I know that I need to get a PCI video card, since my current card only supports two monitors. The thing is, I have 4GB of RAM in my computer but Windows only recognizes 3 GB of it because as it was explained to me, the 32 bit Windows 4GB limit is shared between main memory and video memory. So my 1 GB of video RAM is factored in here, and thus my main memory space is lowered to 3 GB by windows. I'm concerned that if I get a PCI video card, I'm going to lose even MORE addressable space in my main memory.

I guess I could upgrade my system to a 64 bit, but I haven't looked into the cost and assume it would be pricey. Also would my 32 bit apps still work? I get the feeling I would need all new software... which would be a big no thank you.

Anyway, I would value the memory space more than a third monitor, so if anyone can confirm for me that this indeed would shrink my memory space I probably won't bother. But if I am mistaken maybe I will consider the third monitor.
