DDR2 vs DDR3 video card?

im looking at two graphics cards. One of them has 1 GB of DDR2 and the other has 1 GB of DDR3. I need to know which will be compatible with my system. Also which performs better and which is more energy efficient?|||GDDR3 video cards are much better performers than GDDR2 models- usually twice as fast. Higher speed memory like GDDR3 does use more energy. However, newer card designs with more advanced GPUs are often more energy-efficient overall than older models.



As long as your computer has the correct slot type (PCI-Express, AGP) and a strong enough power supply, the type of memory on the card doesn't matter. Your motherboard's memory type (DDR2, DDR3) has no bearing on graphics card compatibility- you can use GDDR2, GDDR3, or GDDR5 cards just fine.



http://www.hardware-revolution.com/mista…|||I don't think there are any graphics cards with DDR3 memory. I think you are confusing GDDR3 and DDR3 memory. These are *completely* different memory types. (In fact, GDDR3 memory is more like DDR2 memory than DDR3 memory.)|||Both will work with your system. The memory on video cards doesn't have to match what's on your motherboard.



DDR3 is faster/more efficient than DDR2, but it won't make a huge different in your overall video experience.|||that's only the memory tyoe. you need to know what type of slot it goes into (like pcie, agp, etc). ddr3 consumes less electricity than ddr2.|||DDR3 has more speed (mhz) you have to make sure your computers compatible w/ it first.|||DDR3 is better in performance but may take up much energy.
