I looking to upgrade my alienware auroa r2 so i can run higher frame rates and on higher quality settings.
here is what i have
intel i3cpu 540@3.07 ghz
8 g ddr
ati radeon hd 5670

I did try to upgrade my video card, I got a
ZOTAC
ZOTAC NVIDIA GeForce GTX 650 Ti 2GB GDDR5 2DVI/2HDMI PCI-Express Video Card ZT-61102-10M

the problem is that this doesn't seem compatible with my mother board.

1)should I upgrade my mother board to be compatible to the video card?
2)should I return the card and try to build a whole new system? (like to keep the spending $500-700 max)
if I do either of the above can I use my existing case and hard drive with windows 7 on it?

3) should I replace with a prebuilt unit?
