Can I Use Ddr3 In A Ddr2 Slot

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

Can I Put Ddr3 In Ddr2 Slot

Due to the different pin design of DDR2 and DDR3, it will be physically impossible to put a DDR2 stick into a DDR3 slot. You will need to have DDR3 RAM. When you buy it, be sure that it runs at 1.65V or less; that's RAM designed for the X58 and P55 chipsets. Anything over running in the 1.7-1.9V range was for Nvidia's 780i chipset.
