Which is better

Unless im missing something that question doesn't make sense..

The Pentium is a CPU like the i5 and i7's do cannot be used together..

Can you explain more so we can help?
 
it's just that I am looking to buy a new PC which is kinda future proof (as far as it can be)

So don't want to buy an older I7 processor if the new I5K processors are faster/better or more future proof..

Cheers
 
Not sure really. I don't play a lot of really powerfull games, as thats why I have a console.. But I do want to be able to chuck anything at it, within reason.

I do use it a lot for PLEX, so need to be able to process the films on the fly as they are being sent to my Roku box.
 
Ahh so you meant:

"Do i buy a 4670k or a 2700/3770?"

Am i right?

It depends on your uses. The Sandy and Ivy i7's had the same gaming performance as the i5's but were better at heavy CAD modelling and video editing due to hypertheading.

So if you're just gaming get an i5 4670k

If you're video editing get a 3770(k)..
 
It is a difficult question to answer as there isn't a black and white aspect to it. Particularly as there are a range of Core i5 and Core i7s in different technologies with different features and different responses to different workloads.
A Core i5 in Haswell technology is limited to 4 physical cores, whereas the Core i7 in Ivy Bridge technology (and Haswell) has 4 additional virtual cores, this aids in highly threaded applications such as photo and video editing/conversion. The -E architecture add increased I/O bandwidths and more overclocking potential. There is also the increased support Haswell has for new technology and standards to consider.

It is very much horses for courses. If you just want something for applications like games that make limited or no use of hyper threading then the Haswell i5 is excellent. If you need high I/O rates and lots of threads the Sandybridge-E or the future Ivybridge-E may be more suitable (or possibly AMD architectures which are excellent at multithreaded workloads). If you are looking at standard Ivybridge i7 as a fresh system why wouldn't you go for Haswell as the price points are not too different and the Haswell architecture is fresher.
 
As you're not much of a gamer I would also add something I only found out recently. I don't know if you have thought much about virtualisation, but the K series of chips do not have a particular virtualisation extension (VT-d) which actually makes them a complete no buy for me.

I just wanted to point this out in case it was something that you may have been interested in (somewhere down the line perhaps), if you ever decided to use this box as a more multi-purpose server.
