Hello Ive been using this site for a while to look up answers without ever opening an account, and am impressed by how comprehensive the knowledge on here is.

I'm building a PC predominantly for gaming (possibly recording as well). I will also be using different CAD software and other modelling programs. I have some questions about my build and whether the choices I am moving towards are correct.

Still a work in progress but my current build specs are:

Case - BitFenix ProdijyM MATX
CPU - 4670k or 4770k
Mobo - z87 Gryphon (Asus)
GPU - gtx 780 (possibly EVGA classified) or gtx 770 (depending on cost)
RAM - 16GB 1600Mhz or 8GB 1600Mhz
HDD - Seagate ST1000DM003 (1TB SATA3 7200rpm) (I may add an SSD once again depending on cost)
PSU - CX750W corsair (maybe a lower Wattage if you guys think thats appropriate)
Cooling - (undecided as of now)

As you can see I have a lot of decisions to make! So just a few questions to help me decide.

1) For gaming possibly recording too and maybe even a wiki page or video open in the background is a 4670K enough? Or would I need HT?
2) Any thoughts of the mobo? It needs to be MATX however.
3) I have heard that you can over clock a GPU, is this going to make that much of a noticeable advantage? is it worth buying a 770 and OCing it or just spend the big bucks for the 780?
4) As I said above for the uses that I will put to this machine is 8GB of RAM enough? or is it better with 16GB?
5) Is it worth getting an SSD now or could I upgrade to one later? Would it make a difference if windows had already been installed on the 1TB drive?
6) Is there any noticeable improvement in speeds the faster the HHD rpm?
7) Is that 750w PSU overkill? And how much difference is there between corsair models i.e. between CX and RM?
8)I have heard that Haswell chips run hotter than previous generations, do i need to upgrade cooling? And is it worth buying the i5 and a nice cooler to allow OCing rather than the 4770K or would this not improve the speed because of the use that I will put this machine to?

Anyway thanks to anyone who has a look at this. Please do answer any of the questions you can.

Cheers

Dan

Wow, you can call that a big project.

Well there are 2 very important criterias ''CAD & Modelling'' -- ''Gaming''
Those 2 normally go well with each other.

One problem you will definitely experience is the case is not big enough to fit every GPU / PSU.

Your max. PSU length is 160mm if you wish to have a high end GPU, GPU can be 320mm in this scenario.
If you have a PSU > 160mm then you are looking at a GPU size of max. 230mm which won't work for a 780 nor 770 as their size is 270mm~.

Are you sure that you are not willing to change the case as well ? Corsair 900D if you need massive amounts of space, or Corsair Air 540 if you prefer going for a full air cooled system.

Let's say you will choose 850W, there many which fit the...

Hi,
-As far as i remember the CAD 2013 doesn't utilize HT, so the i5 and i7 will have same performance, don't know about CAD 2014 though.
-The 16GB of RAM will come in handy for the 3D software
-Z87 Gryphon is good motherboard.
-As for the PSU, it is better to avoid the Corsair's CX units, they are considered as entry or budget units and use low quality capacitors. Better get the HX form Corsair, or something else from: XFX, SeaSonic or Antec in the range of 600-650W
-It depends on your games, the GTX 770 is pretty good GPU for 1080p gaming. Above 1080p gaming, you should consider the GTX 780
-As for cooling, a nice aftermarket air cooler will do the job just fine, something like CM Hyper 212 Evo will allow you for mild overclocking in the range of 4.2-4.3Ghz

1. 4670k (I prefer the 3570k because it gives out less heat/can OC higher) is good enough for gaming. The i7 will add practically no performance hwen it comes to gaming. For heavy rendering/ hosting the i7 would be a better choice though.
2. Idk about m-atx MB's. I know the Extreme 4 Z87 from Asrock would be a great choice though (they also have a smaller version of that MB if I'm correct).
3. If you have the money, go with the 780. You can OC with EVGA Precision. You don't need an EVGA card for this though :p. It is probably the easiest way to OC the GPU.
4. 8GB is sufficient, 16GB if you have spare money. For video editing etc you will really benefit from an extra 8GB, but you can always add this later (a 780 + 8GB compared to 770 + 16GB would be a better choice).
5. You can add a SSD later, but having the operating system on the SSD makes it a LOT faster to boot/ load etc. You can just play on the HDD and later put in the SSD / format the HDD and start over on the SSD. Otherwise just include the SSD when buying it the first time and spare yourself having to format the HDD.
6. 7200rpm is more than enough. I don't specifically know the performance difference, but it probably isn't worth the extra money.
7. RM = upgraded CX. 750w is overkill for 1 GPU, the minimum wattage for 1x 780 = 600w and 1x 770=550w if I'm correct. If you want to go SLI, a good 750w is sufficient (850w to be safe), for 1 GPU 600/650w should be enough (650 to OC and be safe).
8. For plain gaming: 3570k + 212 evo. The 4670k runs a lot hotter/ will need a more expensive cooler for higher OC. The 4770k would be a good choice if you want to include things like video editing.

Hope this helps =).

Let's say you will choose 850W, there many which fit the criteria of <160mm.
I would propose you the following:

i7-4770k --> if you are going to use CAD 'n stuff you want to have as many cores you can get logical or physical.
Depending on the sizes of your CAD projects I would recommend 32GB Corsair Vengance or G.Skill Ripjaws good price tag on 1600Mhz.
Well mobo definitely Maximus VI Gene as there is just nothing better for the price and quality.
GPU well either AMD R9 290X or Nvidia 780GTX both are brilliant for what you want to do.
You want to have a speedy CAD and you want to save quite fast, so I would suggest a Samsung Evo 240GB SSG NON-PRO, just a matter of price, or 2x 1TB WD Black in Raid 0 and you will be fine.

In terms of OC, you are looking at the best motherboard money can buy µATX wise.
So you will be able to run the CPU at a Multiplier of 45-47 easily which will result in 4.5 - 4.7 Ghz without Turbo mode.
I will depend on the cooling solution you want to build in there, as you will be limited as well.
