I bought a Medion PC a couple of years ago that came with a seemingly rare GeForce 7650GS. It has performed adequately in the role of HTPC, but the video was never as smooth as I thought it should be and I was hankering after offloading the increasing amount of HD video processing I was expecting it to do to a GPU. I thought that two years of progress should mean I could get a current low-spec card that would comfortably outperform the GeForce.
After a bit of hunting I settled on a Sapphire HD4350 as being a close match to what I needed. I had looked at the HD4550, but figured that the increased grunt should not really be required and was not justified by the extra heat/power draw.
On powering up the PC with it last night however, I was struck by three things:
1 - The picture quality does not seem as good as older card. Hard to quantify as I spent most of my time looking at the desktop from about 1-2m away - not normal viewing distance for my plasma - but it definitely gave the impression of being a little less sharp. The default colour setting looks a bit washed out as well.
2 - Although I know it is a bit of nonsense, I thought I'd check what difference the new GPU made to the Windows Experience score. To my surprise it dropped the Windows and gaming graphics scores from 4.7 & 4.8 down to 3.8 & 4.1! Surely this doesn't reflect two years of progress in low-end GPUs?
3 - Watching a 720p MKV file for the first time, the thing locked up solid within 2 minutes. OK I thought, maybe it's one of those things so I rebooted and tried again - same thing. I felt the heatsink on the card and it was pretty toasty. I've had various performance and stability issues over the last two years (thanks, Vista!), but never has the PC crashed like this during media playback.
So, maybe belatedly, I figure I should find out if I've maybe made a mistake with this card.
* Shouldn't the HD4350 walk all over the 7650GS?
* Obviously lockups should not happen, but is there anything obvious that I should maybe check or set to prevent them happening?
* Does anyone have recommendations for resolution and picture quality settings that may help? The driver has a load of options for colour format and various other things that I'm not sure I have the patience (or eyesight) to properly test.
* If the HD4350 is not suited, what should I be looking for instead? Any card needs to be silent, have low power draw and include an HDMI port with audio. I should note that this PC has never played anything other than Solitaire, so gaming performance is utterly unimportant - it exists solely for media duties.
PC runs Vista Home Premium and has a C2D 6400, 2GB RAM and is connected only to a Panasonic PX70 plasma via HDMI. I am using the latest Catalyst driver, downloaded yesterday, and uninstalled the nVidia drivers before installing the Radeon card and driver.
