Calculating max graphics card bandwidth

I want to ask you guys that is there any hardware which can capture the difference between PCI-E v1.0 and v2.0? or is there some kind of firmware to upgrade PCI-E v1.0 to v2.0?
Another question i have is that how do i calculate the maximum bandwidth of my video card. I am using FX GeForce 9800 GTX+

I think there is no need to upgrade your PCI-E as both the slots works as same. So i guess you can use both the slots and you can insert any card in v1 or a v2, It does not make any differences. It might happen that there would be something different asked by the card itself but the card which can fit in to v1 can also be work with the v2, that is for sure.

I have some informations about the PCI-E slots. Actually PCI-E 1.0 x16 would be having the same bandwidth as that of PCI-E 2.0 x8. And i think there is no way by which you can convert PCI-E 1.0 slot into a PCI-E 2.0 slot. I think best way to check the bandwidth is to compare some other CPU having the same identical hardwares.

I think you should use the following formula by which you woul dbe able to find out the bandwidth of your video cards.

Effective Speed (MHz) x Memory Bus width (Bits) = Bandwidth (Mbps)

As i have HD 3850 which has an Effective Speed of 1800 and Memory Bus width of 256, so its bandwidth would be:
1800 MHz x 256-bits = 460,800 Mbps = 57.6 GBps

Even i was searching for some way to calculate the maximum bandwidth of my video card and have found that Birdie have given the formula by which i can calculate it. So i am going to calculate as soon as possible but is this formula can really give the real maximum bandwidth of the video card?
