Can I Use Ddr3 In A Ddr2 Slot

The answer lies in the question itself. The RAM in each type is the type that will fit and work DDR2 RAM will fit DDR2 Slot DDR3 will fit DDR3 slot and so on. But in each type they should match the speed of the motherboard / processor. A) would it be possible to use a ddr3 video card to a ddr2 motherboard? And would it affect other components of my computer like i need to buy a new ddr3 compatible motherboard and ddr3 ram, just. As far as the OS, no. However, The number rating reflects the speed of the on-board RAM (in simple terms) on the GPU (graphics processing unit). DDR2 is slower than DDR3, which is slower than GDDR5.

OK! I am a noob at this!
I am running XP Pro 32-bit. I want to replace the Video Card. Nothing great or expensive...just a decent one. It for a friend (senior, that is why XP). I just got him a Dell Vostro 200 slim, added a 1TB HD and installed all drivers and XP. Please let me know 3 things:
1. Does ddr2 or ddr3 matter on the video card..is one better to run on XP
2. 64-bit or 32-bit. I assume 64 will run on 32-bit XP
3. Any suggestions on the card or where to buy (PCI Express 2.0X16)
Thanks! Ynot
