I have Alienware Aurora R5 desktop PC with 512mb nVidia GeForce 9800GT DDR2. I want to add another GPU but can't find anymore a similar card. The closest I can find is a 1gb nVidia 9800GT DDR3. Will the two GPUs work together. Further, will I have to reinstall drivers? Thanks for any help.

Are you sure your current card (9800GT) is DDR2 version?
could you show us the link?

If you are using them in SLI, it' best if they have similar specs. If you are just adding it to get more monitors, they will work together.

Can you list your specs (motherboard) and the purpose for getting another card?

don't Aurora R5's use Asus M3A32-MVP DELUXE MBs? If so I don't think sli is supported, crossfire only I think.

If that's the case, let's hope the OP wants more monitors...otherwise there is no way to use the card for any benefit.

I'm sure my R5 has 512 nVidia 9800GT DDR2. I'm planning to use it for FSX with 4 LCD monitors. I could only find in the neighborhood a 1Gb nVidia 9800GT DDR3. SLI is out of the question anyway because I heard that FSX doesn't kind of "agree" with it.

Alienware Aurira R5 specs from the dealer:

Hard Drive Sata
Hard Drive Capacity 250 GB
L2 Cache 2 MB
Manufacturer Name ALIENWARE
Manufacturer Part Number PC-AURORA-R5
Memory Size 2 GB
Memory Type DDR2
Network Dual Integrated Gigabit Ethernet RJ-45
Operating System Windows Vista® Home Premium 32 bit
Optical Drive Type 20x Dual Layer DVD Burner (CD-RW/DVD±RW)
Processor Speed 2.7 GHz
VGA Controller 512 MB NVIDIA 9800GT

Hope this helps clear up things. Thanks.

Sorry, I did not mention the CPU. It's Athlon 64 X2 2.7GHz.

Open the nvidia control panel and click the help button at the top then click on system information, you will then get a little window opening up that should list the specifications of your card including GDDR type/speed.
