Thanks for the replies.
For the size, more than 7 inches won't fit in my case and motherboard because there are wires and things sticking out of my motherboard to the left of the video card.
I'm not sure what my power wattage is because there are no stickers on the power box.
Not sure what kind of specs I should post but
-Processor: Intel(R) Core(TM)2 Quad CPU Q6700 @ 2.66GHz (4 CPUs), ~ 2.7GHz
-Memory: 4096MB Ram
-Operating System: Windows 7 Ultimate 64-bit
I also would like to avoid buying multiple parts, kind of just want to only buy a new video card if possible.
