Advice for new cpu...

Hi Guys,

I am considering buying a new motherboard bundle and I have not been keeping up to date with computer hardware for over a year now.
Does anyone have any good advice for what kind of stuff £500 could get me? (just ram, cpu and motherboard) or what a bit more or a bit less could do?
I guess I am looking for the 'most bang for your buck' sweetspot, Mainly for Maxwell rendering power
Any news of nice new processors coming out soon?
Thanks

Edit: Does this look like a good option or is the intel 2600k still the way to go? http://www.freshtechsolutions.co.uk/int ... re=default

The AMD "8-cores" are no real eight cores if you compare them to intels cores. It's only marketing...
It's more like quad cores with hyperthreading speedwise.

The AMD FX8xxx can be compared with Intels i7 quads. But with higher TDP and lower single core performance.
But they are a bit cheaper, yes.

I think the best bang for the buck would be an i7 3930K with 16 or better 32GB RAM.
Ever better if you plan to overclock.

if you want it cheaper and a quad is enough for you then the i7 2600K or 3770K

- 2600K/2700K if you plan to overclock, because it stays cooler (the 2700K it's about ~5-10% slower than a 3770K at stock speed)
- 3770K without or with only a slight overclock

take a look at the benchwell scores ;) (but compare them, there are some faulty entries without mentioning the overclocking)

+1

although you'll end up paying ~700€ for cpu ram and mainboard.

the chip is great, and can run stable 24/7@+4 ghz if cooled well.

The next mainstream processor update is planned for Q2 2013 but still only quad cores (Haswell)
The next highend update (Ivy Bridge-E) with up to 12 cores has been delayed to Q3 2013.

Intel has announced a PCIe-based 64-core coprocessor named Xeon Phi to be released be the end of the year.
The only problem is that maxwell will have to support it...
But we'll see :wink:

I'm wondering, for fun mostly, about whether rendering on this type of setup is possible? It's a linux supercomputer built from raspberry pi's:
