HD 4650 Crossfire

Ok I have an HD 4650 card and My motherboard is a Biostar G4I(or 1)-M7.
Only one PCI x16 and I'd like to get something to go from pcie to pcie x16 and then use crossfire with another HD4650. Is this Possible?

If not can I use crossfire with the HD4650 I have and another PCIe card?

How about 2 PCI Video cards and Crossfire?

thank you

Crossfire requires 2 PCIe slots and 2 PCIe cards. I am assuming you want to use 2 video cards for performance purposes. Since you only have 1 PCIe slot you are out of luck for that.

You might be able to use an HD4650 in the PCIe slot and an old ATI video card in the PCI slot. The only purpose in trying this would be to allow 3-4 monitors to be used. Currently the HD4650 in the PCIe slot supports 1-2 monitors. Again since you only have 1 PCIe slot Crossfire would not be involved in this. Whether this works only depends on the video cards used and the driver used.

What if I bought the aforementioned products?
Then will I be able to use crossfire with 2 hd 4650s? Would it be worth it? Would it be better to use a different video card?

thank you

Do you already have both video cards? If you do then the motherboard you mention can run Crossfire with two of these video cards. If you already have both video cards then that is an option. Otherwise this probably is not worth it.

Since the HD 4650 is old now then a better single video card might not only work better but run quieter and cooler. You need to pick one with enough performance to satisfy your needs and wallet.

I have used the information at the following link to help determine what video card upgrade would make a difference.
Graphics Card Hierarchy Chart (Discrete)

Remember if you pick a video card that is not that much faster than what you already have then you will be disappointed when you discover that you can't tell the difference.

You also have to worry about the system you want to use would work well with a faster video card. A slow CPU will hold back a fast video card. Also you need to worry about power since if you choose a high end video card you need to make sure that the your power supply can handle it.

Right now I have an Intel core 2 duo cpu and 4gb of ram.
Would it be smart to upgrade just the video card to an HD 7870?

I read 7870 is a PCIe 3.0 card and I don't have 3.0. This would make it slower right?

What is it you want to do with the upgraded video card?
Only with some information about what you want this upgrade to do for you can we try and give some useful comments.
