like the title says. ive made up my mind and im ordering a 1440p monitor 6ms, pls screen. I am running a 3770k @ 4.6ghz, ram at 2Ghz, and 2 x gtx 670 4gb cards in sli and I need to know if they will run games at 60fps or around (CONSIDERING DIPS)... or will I get below playable fram rate ( below 40fps) at that resolution playing games like bf4, and crisis 3 maxed out on detail?
 
Stating you have all the latest drivers you should be completely fine. BF4 might not get a minimum fps of 60, but nearly there.
 
Ok, processing wise SLI 670s will rape. 4GB VRAM is heaps.

Your only issue may be the platform with 8x PCIe in SLI. Thats a may be. I would test one card at the full x16 and then the SLI and see what the scaling is like.

But to answer you question - heaps of power. You will get dips below 40fps, but you need a machine like mine to avoid that.

4 gigs is heaps atm, 8 gigs of ram is gigantic!
It should be way more than enough for 1440p gaming with latest drivers, although the GTX Titan is the same price and may use less power than an 670 sli setup.

We're talking about VRAM right? Never seen a GPU with 8GB VRAM. Don't mis-quote me again mate - super uncool.

Putting aside the ability for DX11.2 to map system ram as VRAM, i think you're confused.

Secondly, GTX670SLI is faster than a single titan, and power costs are overstated.

It was a correction, an sli setup the Vram is essentially doubled, 2 GTX 670's 4GB = 8GB of Vram

EDIT: Also, when using sli, power requirements would be doubled psu-wise (500W is nvidia recommended for each card), wheras 600W is recommended for a GTX Titan. No the power savings may not be significant but it's a point to make nonetheless when PSU costs are considered.

The vRAM does NOT double in SLI. 2 4GB cards=4GB total available vRAM. 2 1GB cards=1GB total available vRAM. So no, if he has 2 4GB cards, he doesn't have 8GB of vRAM, he has 4. And if he has 2 2GB cards, he has 2GB of available vRAM.

Oh ok, I always thought it was the other way, when I had that sli'd setup in my sig most apps said 2048 vRAM was available, I assumed it doubled in SLI.
Nonetheless they do make 4GB gpu's though.
 
I already have these cards, so suggesting different one is out of the question. yes, I do have 2 x evga gtx 670 4gb ftw+ cards. I have tested the scaling, and with them running at x8 each in the pci-e lanes, they scale right around 90%. example= 1 card @ x16 will get me a score in 3d mark fire strike of 6059. running 2 cards @ x8 will get me a score of 11175. so I think that the cards scale pretty well with just x8 pci-e lanes for both cards.

and correct, 2 of thee cards is more powerful then a single titan or 780ti. and also, correct in saying that 2 cards with 4gb each still only equals 4gb total vram (it does not double).

is it true that if when running a 1440p monitor, you don't have to turn up the AA as much? im just worried about some games not running well, and getting regular dipps below 40fps, as I feel gaming at this low of fps is not enjoyable to me. if they are occasional, then that's fine. id like to average 60fps. I know most games will play fine at this resolution with my setup, but games like bf4, and especialy CRYSIS 3 worries me. I suppose I could always keep mu 25" 1080p monitor hooked up next to the 1440p monitor and just play the games that struggle on the 1440p, on the 1080p monitor.

All of this is wrong.

The power consumption does not double. You add the extra ~TDP of the GTX670 which is 170W. Which is you ran that extra card at all day every day at 100% power draw for a year on a 85% efficient PSU it would cost you $320 @ 22c /kWh.

Most people wouldn't run their cards 100% for 4 hours a day, 3 days per week. The more likely cost would be 13 cents. Totally and utterly insignificant.

Secondly nvidia ISN'T recommending 500W for EACH card, that's 500W for a system with that card in it. The card only draws 170W which MAXIMUM (14A) so a good quality 700W PSU can handle 2 of these easily.

Thirdly, as already corrected, VRAM does not double with SLI/CF. Never has.

Finally, please, when you decide to make a correction, don't modify and present it as a quote attributed to someone else. Its rude and causes confusion.

To Kdfresh,

You won't have a problem on the new monitor mate. IF you do, just turn down the eye candy a bit, or overclock the cards.
