Hey All, So Im heavily considering upgrading my Vid card from an NVIDIA 7900 GS 512 GB to a Radeon HD4870 1GB GDDR5. My question is partially a RAM question, and partially a system spec one. So first, below are my general system specs:
windows vista 32-bit Motherboard with Support for PCI Express 16X (only 1.0)

sound card GForce 7900 GS 512 GB Other un-important PCI Cards 650 Watt Power Supply Question 1: I know im limited to something like 3.2 GB of ram (which is all of my 4 that shows up). Does this expand over to my
video card as well? In other words, will I loose 1 GB of PC memory to use the 1 GB of Video memory? (Will my system know which memory I would prefer to be not utilizing?) Question 2: Are there other bottle-caps in my system that make getting this big a
video card stupid? I was also looking at the Radeon HD4850. Also open to other suggestions as well. Thanks for all the help and I hope the information I provided is complete enough to answer the question. Thanks! -bk edit: O ya, also, I have heard the card is quite large, below is the link to my case:
