Doubtful. What are the psu requirements? It would be better to put the upgrade money towards a newer model computer. You can buy a new computer for the money you have already spent--on windows, memory. Have you tested windows 7 on it yet? It might not be able to handle it or run extremely slow since it's a 12 year old model and obsolete. 

I have a dimension 1100/110. I recently upgraded to Windows 7, I also upgraded the memory on it will this graphics card work? http://www.amazon.com/EAH5450-SL-DI-512MD3-MG/dp/B00612YORQ/ref=sr_1_fkmr0_3?s=electronics&ie=UTF8&qid=1420943336&sr=1-3-fkmr0&keywords=AP4350+512MD2-H+Radeon+HD+4350+512MB+64-Bit+DDR2+PCI+HDCP+Ready+Video+Card

No, the dimension 1100/110 does not support any PCI express x16 video cards, only PCI cards.

You need a PCI video card, like the Sparkle GT 210.

Thanks.  Will this one work? http://www.amazon.com/gp/product/B00ABG6Y2G/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

No, the card in your link is AGP, not PCI that's supported by the Dimension 1100.

Check out the Sparkle PCI video card that's recommended by Rdunnill, Here:

The Sparkle is one of just a few PCI cards based on modern GPUs.
