Template:Nvidia graphics cards
Nvidia graphics cards are currently (Sep 2008) recommended for LinuxMCE 7.10 (also called RC2).
Here is a handy comparison table. And another one- look at the GB/sec of memory transfer as one measure of performance. You can see that the 9400 GT is about 3x faster in memory speed and 3D performance than a 6200 Turbocache.
Simple rules:
- Pick a version of a card which has a fanless design (heatsink/heatpipe only)
- Pick a low profile design to match cases that need the smaller physical card
- Check that the card is the same type as your motherboard slot- AGP or PCI-Express (PCI-E) are usually faster options over PCI cards. PCI-E cards may specify a "1x" or "16x" slot which are different physically as well as in speed.
- Higher numbers tend to be faster (e.g. 9400 is faster than 7200)
- LE is a slow version of a particular graphics chipset
- GS is a slow version
- No suffix is medium speed
- GT is faster speed
- An LE in a higher chipset might be faster than a GT in a lower chipset
- There are other "high end" letter combinations which you don't generally need to worry about as these are 3D gaming cards whose extra performance does not help LinuxMCE
- A card with GDDR3 memory is often about 2x the speed of the same chipset without GDDR3
LinuxMCE needs medium speed 3D and high speed 2D.
The 6200 Turbocache is adequate for SD (standard definition- 576 lines or below) video playback. It is also bit sluggish for UI2 Alpha Blended interface (horribly slow until you kill the photo screen saver). Also not adequate for HD TV broadcasts (720p and above).
The 6600 'probably' has enough horsepower for HDTV and UI2. 6600GT should be fine.
The pick of the current Nvidia line up (Sep 2008) for a full height card is probably the fanless 9400GT, about AUD$80 (US$70). This is still to be verified, as I have one on order to replace my 6200 Turbocache 128MB.
