hi ther i am buying an i7 quad 3770 3.4 but have been informed it will be pre overclocked to 3.5 should i message him and tell him to not overclock or what i have no idea if i should keep heat down or if it does not matter

1) sounds like you are buying from the wrong guy (3.5GHz really?)  but i digress... ha not really..
default speed is 3.4GHz Intels TURBO auto over clocks it up to 3.9GHZ.  that standard default

a real overclock would be 4.5 to 4.7GHz and yes it should be done but only by someone who know what they are doing..
when done correctly its 100% stable.
to do a real OC you need a 3770k

i would be a bit concerned with where you are buying from..

the cpu is locked to 3.5 max he said

definately had absolutely no clue

1) a 3770 is 3.4
2) a 3770K is 3.5
the K chip is for over clocking. @ 3.5 its NOT over clocked

the chip is SUPPOSED to turbo to 3.9 nad not be messed with (unless doing real over clocking)

anyone setting it to 3.5GHz and not allowing it to turbo is well an idiot.
where in the world are you getting this from?

ebay i have just messaged him asking him to leave it at standard 3.4 if u would like to check it out search in ebay 
sphere pc intel core i7 quad core 3770 
i would like it if you could u know what your talking about
and anyone else if you would like to check it out 4 me and tell me what you think would be greatfull.

ive just messaged him again after reading ur post again telling him the chip left alone shud turbo to 3.9 how come he says it locked to 3.5 max .i am looking forward to see what he says if its not something clever im going to have to look somewere else.because it does seem crazy what hes telling me .
ps thanks alot for helping and i am sorrys for herific spelling

your better of waiting till i get message back i will post his response 
and see if im still interested. if anyone know of a good pc for x1 about £400 or less let me know.

Basically it's horses for courses at that price point.

He's basically building those systems around an MSI B75 chipset board. Also it is a 'k' chip so 3.50 Ghz is it's stock speed.

B75 is basically designed for a budget business PC you'd want to put that CPU on a Z77 if possible as you are not going to get much joy of of that board if you did want to OC.  But really you are getting a bunch of parts put together and you'll still have to set it all up yourself to get it working well.  You may or may not be better off sourcing the parts yourself or maybe he can give you an option on z77 based machine.

He's a box shifter and for your budget you might strike lucky.  It really depends on your requirements for a music PC.

Here's the main site for them.

Actually that's quite near me they might be handy for some parts...

hello jonbouy
ive messaged him and he says its not the k chip its the standard (long story at start of thread)
looked on the web site and it turns out there more exspencive wich i dont understand because with ebay you get loads of charges. i dont think i will be oc i just want the system to work as it should and not to be pre fxxxed up because if i wanted that i would have ago myself. the motherboard is a asrock  h61m-hvs would u suggest i ask him to fit a different one. i would be using this in my home studio with roland quad guitar tracks bass tracks vocals some keyboards session drummer and lots of vsts in the end i will be using some midi but im not 2 clued up on that yet just thaught id give you an idea of what i will be using it for i use 64bit x1 record in 24bit 96000htz 

Their e-bay stock looks newer than the stuff on the internet site.

For the money he's charging and what you have to spend I'd say you don't have many other options.  For what you want to do with it will get you going for sure.

Try talking to them over the 'phone first, you'll get an idea of what they'd be like to deal with if you run into problems and you'll get a feel for the kind of operation they are.
