I believe your card has HDMI outputs or at least comes with a HDMI adapter.
Nah, no GTX295 here. Is that all I'd need, is a DVI-HDMI? Okay, that's simple enough. Audio, hmm.
A card with optical out? Or could I work it through an independent sound card rather than the on-board it has atm?
Some of the older HD TV's had DVI inputs but I'm seeing more of the newer ones just having HDMI for the HD signals, so yeah, a DVI to HDMI adapter should do ya.
Not sure what your motherboard supports, as some onboard audio does offer optical out. A seperate sound card could certainly achieve this if your mobo doesn't.
Are you running a seperate audio amp/receiver or do you have plans or are you just going to run TV sound?
