Hi,

I'm going to be searching a second hand bidding site for a cheap intel processor to work my next build around.

will use it for heavy gaming, recording, encoding.

Any good ones I should look out for on ebay that may turn up cheaply?

Looking for i5 or i7

The i5 750 and 2500k can normally be found for £50 and £100 respectively. Motherboards are cheap for both. The i7 920 can also be found for around £50 but motherboards are more expensive.
 
Probably best to not mention ocuk competitors. But depending what your budget and motherboard is the i5 2500K, i7 2600K and i7 2700K are great chips (sandy bridge quad cores, unlocked for overclocking and achieve nice overclocks with relatively cheap air cooling). If you want to spend a bit more, then a second hand ivy bridge i5 3570K or i7 3770k is a bit faster, but will cost a bit more.

If your budget is lower than the level of the i5 2500k, then the older nahalem and lynnfield chips including the i7 920 (D0), 930, 950, 860, 870 and i5 750/760 are available for much cheaper and still offer a lot of CPU grunt and decent overclocking (albeit with higher power usage and an older tech board)

Sorry about the competitor name, I thought that since it wasn't a link it didn't matter. I've edited my post and changed how I said it :)

I think that if i'm going to save up a bit, may as well save a bit more and get an i7.
 
there's different sockets don't forget

1155 Nehalem/bloomfield p55/x58 boards
1156 Sandy/ivybridge p67/z68/z77 boards
1150 Haswell z87 boards
 
Aye, the 4000 series intel chips (like the i7 4770K and i5 4670K) are the ones that work with that board. They are fast, but not particularly cheap (since they only came out in June).

The way the Intel boards work in terms of general CPU compatibility (only mentioning some of the compatible CPUs for brevity):

P55 (LGA 1156): i5 7**, i7 8** (lynnfield)
X58 (LGA 1366): i7 9** (nahalem, gulftown)

P67/Z68 (LGA 1155): i5 2***, i7 2*** (sandy bridge) / i5 3***, i7 3*** (Ivy bridge) (though for Ivy bridge compatability boards need a newer BIOS version and there are some that don't work with ivy)
Z77 (LGA 1155): i5 2***, i7 2*** (sandy bridge) / i5 3***, i7 3*** (Ivy bridge)

Z87 (LGA 1150): i5 4***, i7 4*** (Haswell)

All the chips mentioned above are quad cores, the i5 have no hyperthreading and the i7 have hyperthreading.

x79 is an expensive option unless you know you require 6 cores or lots of gpus. 8Pack said somewhere that the 4770k is the most powerful cpu at the moment for gaming or normal users.
 
I personally wouldn't get a 4820K. It is still only a quad core and it is only an Ivy Bridge designed core (the haswell chips like the i7 4770K are faster).

Plus, with the 4820K you need to buy a X79 board - which are quite expensive (cheapest one is £153 on OCUK).

Since the Haswell 4770K is only £20 more for the CPU and the motherboard (like the MSI Z87 you linked to) can be much cheaper - more than making up for the higher CPU cost.
 
Would someone mind speccing me a decent i7+ mobo selection and a decent i5+mobo?

Just would like to know the difference in price.

thanks
 
What motherboard features are you needing?

For example:
- how many SATA ports (and particularly SATA6 ports) do you need?
- how many USB3 ports do you need?
- Do you want a board that is OK at overclocking or amazing?
- How many PCIE ports do you need?
- Do you plan on running two or more graphics cards in SLI/CF?
- Do you need any PCI ports for older devices?
 
the haswell is also very fast at stock so you dont need the k version. I bought the 4770k and run at stock so my pc case stays near silent; between the cpu and the motherboard i could have saved quite a bit of money going for non overclock versions....oh well.

Click to expand...

1) Not to many really, any mobo should have enough. (I'm only using 2 at the moment)
2) My case has 2 front panel usb 3, so will need to be able to use them.
3) Ok at overclocking (unless having one thats amazing at overclocking is not too much more)
4) 2+
5) It's something I would like, just encase.
6) No I do not
