3930K or 3770K or 2700K

post #1 of 36
Thread Starter 
Building a high end pc which processor should i pick
İm gonna be using 2 x gtx 670 1920x1080 res. Is 2700K enough?how much fps difference will i get with 3930K.i think of overclocking and heard 3770k isnt great but 4.2GHz is good enough for me.gonna cool with corsair h100.

Also can any of you recommend a good website for shopping for my stuff.They need to ship worldwide cos i live in turkey this place is like forgotten and prices are sky high a single gtx680 costs 700 dollars lol

Thanks to all who spares their time

I you fold and/or need the cores for things like encoding and PCI-E doesn't matter to you go with the 3930k. Otherwise the 3770K.

No, don't just go with a 3930K. He wants to use two 670s. X79 only supports pcie 2.0. You will be getting a 1/2 the bandwidth running on card, and 1/4 the bandwidth with two cards when compared to a full x16 pcie 3.0. The 3770K is a great chip for the price. If you're gaming, you'll hardly notice a difference.

What are you going on about? First it's twice less the bandwith no matter how many cards you put in or lanes there are. >.> Basic math.
Second, PCI-E 3.0 isn't yet nearly utilized enough to worry about it, so far we're only seeing minor improvements, in the percentages, maybe a 1% or 2% speed difference. And if he were for example to add another 670 there, a faster and more powerful processor would help him reduce bottleneck if he's not gaming on extreme resolutions, in which case CPU is almost never a bottleneck.

What, where did you pull that from?

Also no desktop GPU's today use the full PCI-E 2 bandwidth...

Well we are seeing some improvements when people test 2.0 vs 3.0, at least in the test I saw, but they are really minor.

Also on PCI-E 3.0 on X79, I didn't knew that, I had the impression only Ivy was Gen3 for the whole set. Didn't know Sandy-E had 3.0. tongue.gif

Sorry I'm on my phone today and it decided to cut out the "3" when I typed PCI-E. X79 doesn't support PCI-E 3. I didn't see anything about dual 670's.

None the less my original reply still stands, unless you need the extra processing power of the SB-E, go with the 3770K as if this is purely for gaming you are better off with the IB.

Quite easy Choice... 3770k..

3770k 340$ Vs 500$ 3930k in over 50 bench marks. http://www.anandtech.com/bench/Product/551?vs=552

Then you have to add Avg cost of z77 mb around 150$... Avg cost of x79 mb 300$

The only Reason to go X79 would be for the Highend IB chips... or if your going to SLI more then 2 Gpus. other then that it is a waste of money vs z77 as the benchmarks show.

Thats why i went 3770k and not SB-E.. Bench marks don't Dont show it worth it.. As they are pretty even in performance.

Now depending on how the High End IB chips perform i may upgrade to them when they come out.. But once again ill use Andtech Benchmarks price and reviews to make my choice.
