I have an HTPC running with Vista Home Premium. The monitor I use is an XHD3000 which has a native resolution of 2560x1600 (and you can access the goodies such as PiP at that resolution only). So I wanted a video card that would replace my GeForce 6200TC. My only req is that it be passively cooled and supports that resolution and be able to accelerate 1600p. I read that the HD 3450 chokes at 1440p. The HD 3470 might be able to support that resolution when decoding blu-ray. Does anyone have a recommendations or thoughts about this?
