Can an EliteGroup 945GCT-M3 run a Geforce 440 GT graphics card?

@software_ss,

The motherboard doesn't need to have PCI Express 2.0 technology, in order to support a graphics card based on the PCI Express 2.0 technology.

This is because the PCI Express 2.0 technology is Backwards Compatible, with PCI Express 1.0a, and 1.1 technology. Doesn't always 'play nice' with PCI Express 1.0a, but this why PCI Express 1.1 was developed.

So stating a PCI Express 2.0 graphics card, will work on a motherboard with the PCI Express 1.1 technology, is PERFECTLY FINE.

Using a motherboard with the PCI Express 1.1 technology, you will NOT get the full capability of a PCI Express 2.0 graphics card.

This is because PCI Express 1.1, has a PER LANE data rate of 250MegaBytes per Second, (250MB/s), and a TRANSFER RATE of 2.5GigaTransfers per Second,
(2.5GT/s)

PCI Express has a per lane data rate of 500MegaBytes per Second, (500MB/s), and a transfer rate of 5GigaBytes per Second. (5GB/s, or also stated as 5.0GB/s)

So what does that mean in reality? Let's say you are playing an intensive game, and using a 6 foot HDTV as a monitor. You may not see the characters in the game sweat, and maybe, just maybe, there might be frame rate lag.

In otherwords, I DOUBT you will notice. We haven't reached the full capability of PCI Express 1.1 yet, don't let them fool you.

@ joecoolvette, Thanks brother for detailed information. I knew something like that (the graphics card should support but not with full features, not all of these) , but did not know the purpose of his target to go for the update. So, I mentioned about 2.0 to get the full feature if he wants to supported. This information is really helpful for me, because I did not study on data transfer rate of pci express. Thanks again. @ joecoolvette, Thanks brother for detailed information.
