As above does such a beast exist, I currently have a 7600GS Nvidia I think, I think it is 256mb but not sure on the exact specs, I want to upgrade this and I am got quite ready to ditch the old acer desktop in favour of one that can take PCI-e cards just yet. I am running 1gb of ram currently if it makes a difference, I want to hook this PC to my Sony Bravia TV if possible, I have an after market sound card with upto 7.1 channel but would prefer if the sound ran thru the TV via HDMI if that is possible.

Does anyone know of a graphics card that is an upgrade to my current one, wont need a bigger power supply to be purchased from the standard one I have and has HDMI output, not much really !!! oh and can send the sound thru the HDMI as well.
