Ok, so it has neared the time that I am going to build my rig. I have a couple of parts that I want to make sure are going to work with each other. So, I would like your opinions.

The mobo I am looking at, is a:
GIGABYTE GA-MA770-DS3

And the graphics card I am looking at is a:
ASUS EAH3650

Is Direct X 10 going to work with XP?

Also, one thing that I want to know: is that more graphic card than I need? I am not a gamer, but I do do a lot of video editing in premier pro, and a lot of photo editing in photoshop CS3, and animation in After Effects.

Thanks for your opinion.

Any particular reason(s) why you chose those two items?

I don't know how much it matters, but Adobe recommends nVidia cards:

Have you considered a board with integrated graphics? Possibly a board based on the GeForce 7050 chipset or maybe the AMD 690G? You could always add a card later if the integrated turns out to be inadequate.

"Is Direct X 10 going to work with XP?"

No, DX10 is not supported by XP, but you can still use a DX10 card.

Ok, found another one:
ZOGIS ZO96GT-E

It is an nVidia card, and it has a lot of power.

I have several reasons for not getting integrated graphics, and I want something faster than what integrated will give me.

Yes I think it is a wise choice not to choose a integrated graphics.

Is it possible to use a PCI x16 card in a PCI 2.0 x16 slot?
