Video Card Slot Question

Ok. The 2.0 refers to the version of PCIE standard the slot or card is. There actually is a 3.0 standard now though I don't know that it is actually in the wild yet. I know the standard exists but I haven't looked lately to see if any manufacturer is producing it yet. The standard mainly governs the data speed or bandwith of the slot with higher version = more speed. The x16 refers to the physical size/length of the slot. x16 slots are the longest. *Generally speaking*, the standards are backwards compatible and a higher version slot can handle lower version cards and vice versa. The lower standard being used will determine the speed things flow at. Now many, if not most all, of the top-end cards do take two slots. However, that just means the card is a 'double-wide', and needs two slots in the case. It still only requires one PCIE slot to plug into but if you have any sort of slot right next to the PCIE slot, that one will become unavailable for use. The reason they're so fat is because of the cooling apparatus on the card to keep the GPU from melting is large and needs the extra case slot to fit. So when considering upgrading, that is something you'll have to take into account. The new cards can also be kind of long, so be sure you have room in that direction too. Do your research before you buy to be sure what you want will actually physically fit. All that said, assuming it will physically fit, the card you link should work. Just know that it is PCIE 2.0 and if your slot isn't, then there's a small chance you'll have issues, and if it does work, it won't necessarily work to it's full potential since it will be slowed somewhat by the slot.
It is known that there are an infinite number of worlds, simply because there is an infinite amount of space for them to be in. However, not every one of them is inhabited. Therefore, there must be a finite number of inhabited worlds. Any finite number divided by infinity is as near to nothing as makes no odds, so the average population of all the planets in the Universe can be said to be zero. From this it follows that the population of the whole Universe is also zero, and that any people you may meet from time to time are merely the products of a deranged imagination.
And I should have said though it matters little here, that the x16 also refers to the number of lanes the slot has, which does affect speed too. But as video cards are normally all x16, it's a minor point for this discussion. I need to proofread better...

Okay, usage of 2.0 is sometimes inconsistent.
Assuming a "PCI-E x16" slot is NOT 2.0, it's getting roughly 250 MB/Sec throughput on each "channel/lane". This works out to about 4 GB/Sec.
PCI-E 2.0 doubles the amount of data that can be transmitted per-channel/lane.
So a PCI-E 2.0 x16 slot is getting roughly 500 MB/Sec throughput on each "channel/lane". This works out to about 8 GB/Sec.
PCI-E 3.0 is using some different terminology. They're now talking about Gigatransfers instead of bits per second. It still breaks down into another doubling of lane/channel speed to 1 GB/Sec. Meaning a PCI-E 3.0 x16 device on a 3.0 connection would have a maximum throughput of 16 GB/Sec.

Is it perhaps me being mistaken that the slot is not categorized this way, and just the card?
My mobo is an ASUS P5BW-LA, and it just says the slot is PCI-Express X16, not v1.0, v1.1 or v2.0.
Maybe only the cards are categorized this way.

No, the slots are categorized that way as well. Your mobo is 1.0.

If the version isn't stated, most of the time it's 1.0.

What are the differences between a PCI Express x16 slot, and a PCI Express 2.0 x16 slot?
Does that just mean the card will take up 2 slot spaces?
I put in a new power supply that has the capability of powering a new generation of video card, up from my current NVIDIA GeForce 9500GT. But I only have one PCI Express x16 slot on my mobo.
Would a card, like http://www.newegg.com/Product/Produc...annel&CMP=OTC- this one, not work at all?
If it doesn't, can someone suggest a vid card that would?
