Is the i7 5820K a good choice for a CPU and best X99 motherboard under £300?

The 5820 makes sense as long as you are doing no more than dual SLI and not hanging a whole lot more off of the PCI-E bus besides.

Otherwise it could be an excellent value. On average the performance difference between the 5820 and 5930 is around 5% based on some of the initial published benchmarks. So if you are doing single GPU and/or willing to accept a SLI configuration at x8 you can save 20% of the cost of the 5930 while giving up only 5% of the gross compute performance.

In SLI you'd only get 1x16 and 1x8, so scaling wouldn't be as good as one would hope out of an "E" series processor. If you're going to run a single GPU, I'd say the 5820k is an excellent deal. If you want to run SLI, I would seriously consider the 5930k to run 16 x 16.

yeah I think vellinious hit it on this one. if you are for sure going to be adding more than one graphics card and or a video card plus 2 or more pci express cards then you can start looking at the 5930k, b/c it seems the 5820k is only slightly less speed in terms of MHz less but yet they both can be overclocked so it's almost a tie with that aspect. I'd say if you don't mind spanding 600 dollars for the 5930k then you should probably consider spending 400 more for 5960x and get 2 more cores plus your 40 pci lanes.

what it has been in the past was the the 4930k was the sweet spot with 6 cores just like the 4960x and almost as fast but a 400 dollars cheaper. now most people will be falling under the 5820k or the 5960x and the 5930k doesn't seem as attractive.

when I was picking my parts I was considering this choice and intel did a good job of giving you options and price points this time around. Since I am only going 1 video card as I have done in the past, the 5820k was my choice.
