I recently purchased a Radeon 7000 64mb PCI video card.
Currently i have 384mb of SDRAM. After installing the card i still have 384mb, should i not have 448mb? The video adapter says its DDR SGRAM/SDRAM.
Right click your desktop, (takes you to Display properties) > Settings tab > Advanced > Adapter tab. Usually on Windows XP and 2K systems, the RAM amount will always show up there. If not, another way to check is DirectX properties (C:\Program Files\DirectX\dxdiag.exe) > Display tab.
