Lewer, to be fair, I have not used the Quicksync myself.
I currently use AMD CPU - an FX-8350 8 core, overclocked to 4.6 GHz. It doesn't have Quicksync as that's an Intel feature. This CPU is in the price range of the Intel i5 .
My GPU is an nVidia GTX 560 Ti , and it renders about twice as fast as the CPU. I tested a top of the line nVidia GTX 690 that I bought at the store and saw zero improvement in rendering speed unfortunately.
The Intel mobo and CPUs are pricier. And Intel has a bad habit of changing their socket seemingly every year.
I don't think the SSD caching support on the motherboard matters at all. Just add a bunch of RAM and let the OS do the caching. I have 32GB which allows many of the video clips to stay completely cached. This makes for extremely fast editing. However, it does nothing for rendering speed.
The reason my SSD is very fast is that it's two SSD in RAID. Both of them are SATA III (6 Gb/s) . The max read speed on SATA III is about 600MB/s per port. Effective on the SSD I have (Crucial m4) is about 450- 500 MB/s . But when using RAID-0, you double that. So it's 900 MB to 1 GB/s. Of course the SSD is only 256 GB. That's small, so my video clips are mostly on the HD (4 TB RAID). But again the OS does the RAM caching for the files on the HD as well.
The nVidia GTX 690 was supposed to improve encoding speed with the nvEnc chip (google their press releases on nvEnc). But apparently the support for PowerDirector still has not been enabled. That's why I returned my GTX 690 to the store. Perhaps some day they will enable this support in PD finally.
I personally will wait for faster GPUs to improve the encoding speed.
I do have two machines on a KVM. The other is an AMD Phenom II x6 OC at 3.6 GHz and with 16GB of RAM. So I can use both to render. The HD/SSDs are shared through Gigabit ethernet. This way I can render 2 projects at once if I wish.
