Plugging ddr2 graphic card in ddr1 motherboard

The motherboard will only determine what type of DDR RAM needs to be installed, not what type of memory is on the video card so yes, you can put any video card on that motherboard if it fits. What type of motherboard do you have? brand and model number please.

The memory on the graphics card and motherboard are not related.

If you have DDR on your motherboard, I think there is a distinct possibility that your computer will bottleneck most modern graphics cards.

What are you trying to do specifically? Do you have an AGP slot or PCIE? How much are you looking to spend?

i have d865gbf motherboard with 2.4ghz p4 ram 1GB HDD 120 gb i have agp slot and also suggest me the graphic card

What is your budget?

I think this is the best AGP GPU out, but you will be bottlenecked by your CPU with it anyway.

That's the same card I was thinking - definitely 46xx range is as high as I think you can go with AGP, but as stated, it will more than likely be bottlenecked by your CPU.

If you can spare some more money, it may make more sense to update the entire system - there are some really solid budget systems out there that will give you some good years.

It depends on your budget and what you are looking to do with it.
