If you're building new, performance-oriented box, you should take latest |
22 |
intel with AVX because of AVX. As I recall, recent gcc has support for |
23 |
avx, so some performance gain may be achieved. |
24 |
If you want home box, you may be interested in AMD A8 and similar chips, |
25 |
as they are reasonably fast and very chip |
26 |
|
27 |
In any case, I'd put most of my money in 2-4 big 3Tb HDD's for media and |
28 |
8+ Gb fast memory, as modern browsers eat memory like crazies and CPU is |
29 |
usually fast enough. Decoding HDTV mkv's should occur on gpu block in |
30 |
any case, so general performance for most uses is irrelevant, as it was |
31 |
fast enough four yesrs earlier. Simply check, that you can offload HDTV |
32 |
decoding to GPU in your config. |
