The GeForce GT 220 is inexpensive and seems to have what I need. But I don't mind spending for a premium card, I just don't want to spend unnecessarily on capability built for PC gaming.
Here are some of my questions:
- Does more memory (e.g. 1GB vs. 512MB) help for HD video viewing? Or does memory just matter for gaming?
- Is GDDR memory a better choice than DDR2 memory for HD video viewing? What about GDDR2 vs. GDDR3 vs. GDDR5?
- What other video card features are important for HD video viewing?
- Any suggestions for a specific card?
I think perhaps some clarification is needed here?
Yes, more memory helps with viewing video if you've only got a small amount. 2GB is good, 3 is better for an htpc. Of course, 4 or more won't hurt, but you're not going to notice any increases in performance as there are none to be had after a certain point... either playback is seamless or it is not.
As stated earlier, GDDR is graphics DDR, and it's what comes on the video card. Do not concern yourself with the type of memory the graphics card has, whether it's GDDR3, 4 or 5, because at the end of the day, it matters very little. While it's true that in theory GDDR5 can reach speeds much greater than GDDR3, in reality, the performance between a GDDR3 and GDDR5 card are about the same because the memory interface is different. A GDDR3 card with a 500-bit memory interface is going to be just as badass as a GDDR5 card with only a 256-bit interface, even if it's clocked higher.
As for "which card", you should take some time to consider what ATI/AMD have to offer if you're really only doing this for an htpc. With ATI, you can output the sound through the hdmi, whereas you cannot with an nvidia card.... something to consider.
HD viewing in practice does not really require a whole lot of graphics power... even an older X800 does a really good job of outputting video (brother in law does it with this card). Do a little reading, see what fits your situation best, and don't think you have to spend oodles of coin just to have a good experience.
