Should I get another 780?

With the stock cooler, two do look very good together.

Plenty of power now on tap

Recently went SLI and while it's an amazing experience I do get frame drops on my i5 (Going to an i7 soon) and I have GPU usage issues because the i5 doesn't have the threads for it.

However The games look amazing maxed, my fps is higher and thats all you need to know.

Top card WILL run hotter and as such make slightly more noise but once your in game you wont notice. Just make sure your case has decent ventilation.

Which I5 and which I7? I was never under the impression an I5 bottlenecked an SLI rig.

Would be interesting for me to look into because I'm running a 2500K and a 690

Its a thread bottleneck brought on by all round intensive games like bf4 & crysis3...i5's simply don't have enough threads to keep up with dual cards.

I had the same with an i5 3570k and sli 670's. Switching to a 3770k helped. Found i got low card use and high cpu use and a lot of stuttering. Was able to replicate it on the cpu in sig with the same cards by turning of hyperthreading in bios.

Hmm thinking of moving to 780 sli soon, I take it my 2500k won't cut it then and will be a bottleneck. How big of a bottleneck will it be?

Wish I had £400 to drop on a graphics card. Marriage and mortgage put paid to that though :/

My 4770K should be fine to handle 2 780s, I'll clock it a bit higher too (probably to 4.6 GHz).

As long as you overclock it to around 4.5-4.6, you should be alright I'd imagine.

4.5ghz Ono should be grand on the 4770k. I found mine at 4.2 coped great with my less powerful 670 setup. Planning on 780 sli eventually as well.

Just finished my 4770K build with 3 Titans - 4.7Ghz seems to handle them nicely

Yeah unfortunately it really does

I've only done dual card runs at 1.212v. If I can muster the energy this weekend I might give you a run and fail miserably but I'll probably be asleep for the most part

PhysicsMan94 · 24 Jan 2014 at 13:34

Vcore on my 4770K is at 1.152V for a 4.2 GHz OC if I recall correctly, hopefully my chip is a good one - haven't tried OC'ing it higher than 4.2 yet.

1.152 is pretty good, id try bumping it up a bit. Unfortunately mine is a bit of a lemon. 1.267v @4.5ghz and will hit the mid 90's if stressed with p95 etc. Thought about delidding it but may wait and see if i can pick up a better chip on members market or somewhere. Temps in game are fine though at 67c max in a poorly cooled case.

PhysicsMan94 · 24 Jan 2014 at 16:33

Indeed, I don't really need to worry about my CPU temps as I have it watercooled (gets to maximum of 45 C when heavily benchmarking at my current clock speed); it's my 780s that will be the limiting factors with regard to temperatures, eventually I'll get around to getting them under water too... maybe

setter · 24 Jan 2014 at 16:35

At least on the maximus VI extreme, you'll have better slot spacing than my formula which will help a lot with air cooled cards.
