Is this graphic card good with my computer?

[shekkieface]

I have a Hp Pavillion a1640n and I have chose a Graphic Card and a Power Supply Unit.
I want to know if this is a good choice because i'm looking forward in the future to use SLI and I don't want to buy another graphic card cause it's outdated or another Power Supply cause the Watts are too low. I'm planning on buying the same graphic card twice. Can someone tell me if this is a good choice on my computer? I am not made of money and so if someone can recommend me better pieces I would be glad to check them out, but if it's something expensive..sorry...

What GFX card and I very seriously doubt that an HP can use SLI....

Yeah those would work nicely in unison but what are your computer's specs?
