SLI Worth it?

Specs in sig, mate of mine bought the same card as me (Asus GTX 670 4gb) But he is going for a 780 because he can the lucky boy. I thought I could buy his card of him to run in SLI. Both our cards clock the same at 1202/7008

My question is SLI worth it, I have heard about micro-stuttering and to be honest I have no idea what it is!

Or should I just keep what I have and be done with it for a few years:confused:
 
That would be 8gb not 4.
But I had 2 evga gtx660ti in sli, thats almost same card as 670, and didn't see big improvement.
Probably not really worth it.
 
OP if you can pick up your mates GTX 670 cheap, then go for it.

Just don't tell your mate that two GTX 670s are a bit faster than a single GTX 780.:D

If you can go SLI then go SLI, Really nice experience be8ing able to turn everything to max detail and rez and having 2 cards is kick ass :D

Still only 4GB, the GPU memory is shared meaning if you have 2 x 4GB cards you have 4GB total, Would be awesome if it was cumulative but it isn't.
 
I was going to go down the SLI 670 route but after a lot of back and forth thinking have just ordered a EVGA GTX780 FTW ACX for a really good price. It's not as fast as a 670 SLI set up but i won't have any potential problems plus SLI would be wasted in some of the older games i have been playing recently. I won't have to re-do my water loop either.
 
Depends what sort of price you can get it for. Should be a good upgrade though and NVIDIA tend to have a particularly smooth experience in SLI due to the built in frame pacing hardware the cards have. SLI 4GB 670 > single 4GB 670 for two years certainly.
 
As you have the 4GB go Sli, l have a Sli 4GB 670'S paired up with a 27" 2560x1440res monitor, has giving my gaming a new lease of life.

Loving my Sli 670 set up.:D
 
Another reccomendation for sli. And as the cards are 4gb models so vram use wont be an issue. Ive considered selling mine, but tbh theres no single card worth currently moving to.
 
Hmm looks like he will do it for £150, I can have it asap and pay him off in chunks ... Thanks for the help all. Certainly not worried about the vRam thats why I bought the 4GB in the first place "just in case" ;).

I have heard people complain about micro-stuttering and after reading up on it I can see why It would annoy some people, however I watched a video of someone showing MS and I honestly could not tell what he was trying to show so maybe its slightly subjective to the person.

I do play some older games but I could just disable SLI for them if it's not supported or worth it right?

Also while our cards clock the same, I've noticed that mine likes to hit its power limit and throttle back by 13Mhz every now and again, His doesn't, Do SLI'd cards have to run the same clock/memory speed?
 
Do it!!

I had 670s in SLI and they were awesome, unfortunately I only had the 2GB versions so was running out of vram @ 1440p.
4GB versions would give better performance than a 780 ;)

Edit: you replied while I was writing post.

Both cards don't need to run the same speed.
You can enable and disable SLI anytime, there is an option in the Nvidia control panel
Very few people notice micro-stutter and Nvidia have made it almost impossible to notice. 670s benefit from tech that almost removes it completely

Speed wise theyll run at their own idividual boost speeds. Eg my top card has a stock core boost of 1189mhz, bottom one is 1150mhz.
 
Well like i said both our cards clock at 1202mhz on the core and 7008mhz on the memory (we spent hours on TS overclocking at the same time for the luls) just mine likes to hit its power limit and very slightly throttles and his doesnt, It's good to know that if there is a slight discrepancy on the clock speeds between cards that it wont effect anything!

make sure to put the one that doesn't throttle into the top slot...

It Always best to put the fastest card in an SLI setup in the top PCI-E slot...
(The PCI-E Slot closest to the CPU if it a desktop case / HTPC case / ETC )

Alrighty, even had to add a modded bios to my card to increase power target to 135%(from 122%) fixed the throttle issue for 95% of my games for example BF4 stable @ ultra settings with 4x msaa @ 1080p 60fps avg with slight dips to 50's thanks to shadowplay

but farcry3 likes to make my card go over the 135% power limit, tried lots of different limits but none help
