</div>My thought was that VAAPI doesn't seem to work properly with Sandy<br>

there are many other rough spots. But since Ivy Bridge supposedly cuts<br>
way down on the tearing and has better linux support, maybe VAAPI would<br>
work with it.<br>
<div>> VAAPI is supported, however it is not as refined a solution as VDPAU.<br>

</div>Is the 440 OK? I thought from the numbering it would be better than the<br>
430, but maybe not. ASUS says it has 96 CUDA (cores?). It seemed good<br>
that particular model was fanless and supposedly cooler.<br>

</div>Thanks for the tip. I'll have a look at the Celeron. As I said, I need<br>
something with enough power to run Windows (Vista), and it would be nice<br>
if it could do commflagging and transcoding too.<br>

<div><br></div><div>You will find that the Celeron G530/G540 will perform well enough for most builds right now... and will certainly run Wndows 7 just fine. Additionally you will have far less problems getting VDPAU working then you would VAAPI.</div>
<div><br></div><div>Then a few years from now, you upgrade your processor to an 8 core i7, and 16GB-32GB of 2000MHz ram and you have a system that will easily last you another few years. The key is the motherboard, make sure it supports the Ivy Bridge and the fastest ram speeds available... get a board with 4 ram slots and fill two now and two later for a more incremental build.</div>
<div><br></div><div>Essentially, my motherboard, CPU, and RAM cost me under $140 (I just purchased them last week), barely more than you'd spend on processor alone. And in a couple of years I can replace the processor about $50 and have a killer 4-8 core i7. If you find a board with 4 slots, you could go to 32GB.</div>
<div><br></div><div>My Build, prices after rebates/discount codes/shipping from various vendors:</div><div><div>ASRock B75M $66.81</div><div>Intel Celeron G540 $44.04</div><div>Patriot PV38G160C9K $24.99 (2x4GB 1600Mhz)</div>
</div><div>Zotac ZT-40703-10L $39.99 (GT 440 - ebay)</div>
<div>Total: $175.83 </div><div><br></div><div>I could easily have spent that much on a just a processor... but then I would have to get VAAPI working now, when it's support is only so-so. Far easier to skimp on the processor and go VDPAU and let VAAPI mature a bit more. In the meantime, my motherboard/ram are ready for the upgrade.</div>
<div><br></div><div>Either way, it would be almost impossible to build a system today that wouldn't support Mythtv quite well (assuming you use a VDPAU supported Nvidia GPU).</div><div> </div></div>
