So I bought and the graphics card is here, its a ASUS 3GB R9 280X, and I ordered a VGA to DVI-D adapter in hopes it will work, but now I'm getting really worried it will not work.

VGA to DVI-D? That would be a somewhat expensive and unusual bit of kit since most displays have a VGA port and you would likely be better off doing VGA-VGA.

Are you sure you did not mean DVI-I to VGA? The DVI-I port on the GPU has all the necessary VGA signals for both VGA and DVI-D, all the DVI-I to VGA adapter does is wire the necessary signals from DVI-I to the DB15 VGA connector. As Sig said, tons of GPUs come with one of those included.

If both of your displays only have VGA input, you may need an active HDMI/DP/DVI-to-VGA adapter - not 100% certain about this but I think most modern GPUs can only drive one analog (VGA) display at a time.

I really hope so, I'm gonna wait for more replies before having a solution to this. cause I have 2 monitors and I will not go back to having one. I hate it. But thank you.

I mean what I said, The GPU don't support VGA itself, so I ordered a VGA-to-DVI-D and I started getting worried it won't work, cause I use HDMI for one, and VGA for the other. and I didn't have money to buy a full cable. but Thank you.

One monitor is HDMI and VGA the other is VGA and DVI, But I didn't have the money to purchase a DVI cable. Also, It showed up, It don't work.

If you really ordered a "VGA to DVI-D" adapter, which would mean an active adapter that takes VGA in and outputs DVI-D, I suspect you attempted to use it backawards.

You can get a 10' DVI-D cable for less than $10 from places like Monoprice. If your "VGA to DVI-D" adapter really is what it sounds like it is, I suspect you paid a fair bit more than that for it.

Here is part of an article I found concerning those types of Adapters:

Pros and Cons

The benefit of using a DVI to VGA adapter is that you won’t have to buy a new monitor in order to use your new video card, but there is a trade-off. Because you are using the adapter, you are downgrading the DVI signal to make it work via VGA. This means you aren’t getting the best quality output from your new video card, which kind of defeats the purpose of upgrading in the first place. It all depends on what your personal preference is and if you’re happy with the end result, then you might be able to hold off on buying that new monitor for a while. If you’re upgrading your video card for gaming purposes, then you really need to splurge on a good monitor, too. Why use a DVI to VGA adapter to choke the potential of your new gaming card?

In most cases, the quality degradation going from digital to VGA is not perceivable unless the display has trouble accurately recovering the pixel clock and aligning all three channels. The main reason people upgrade GPUs is to game either at higher resolution or higher frame rate, and unless you want to game at resolutions beyond 2048x1536, VGA is capable of handling the usual 1920x1080/1200p60 as well.

BTW, the Asus R9-280X (at least the model I have looked at) has 1xDVI-I + 1xDVI-D ports, so one of the two ports should support DVI-to-VGA using a simple passive adapter to patch the GPU's analog channels through to the VGA pins. OP could also use a DVI-to-HDMI adapter instead.

Well, I've always read that it mostly depends on the size of your display. You can't really tell the difference if your monitor is 22" or below but it becomes noticeable or screen sizes larger than that.
