Talk me out of 670 SLI

post #1 of 76
Thread Starter 
Can anyone give me a reason to not get two EVGA 670 SC in SLI? Two will beat a single 780, seeing as a single 670 SC is on par with a 680, a 690 and Titan. I want to future proof this rig for BF4 and get more FPS now in BF3. This is also a cheaper alternative as I already own a SC 670 already that EVGA gave me in a RMA for an upgrade over the normal 670 which burnt out to heating issues.

I think it's worth it, however why don't you stick with just one until you need two biggrin.gif -> Waste of money if you REALLY don't need it, as far as I know if you are single monitor gaming just the one is fine. smile.gif

I run a 120hz monitor so dips to 75 FPS in CQ is just unacceptable!

If you don't really need it now then don't bother unless you got some extra cash burning a hole in your pocket.

go for it.... I'm trying to decide between SLi'n my 660 Ti or my 670...
but when and if the 7 series is 'all that' then I will sell off the older cards to get the new..

Hehe, 120hz smile.gif I just used to turn a few things down to get 120fps .. but it's only AMAZING for FPS In my opinion, and I play all FPS with everything off anyway. But yea, if you have extra go for it! But.... unless you are getting lag no point smile.gif Although I did just buy a second 580 for Crysis 3 so what would I know >.>

It has 2GBs of VRAM, investing $700+ into two cards that only have 2GBs each will mean that they won't last you as long as perhaps two 7950s or 7970s due to it's relatively narrow memory bus width which means that even if you go for the 4GB 670's you wouldn't really be able to full utilize all of the available VRAM; even if your cards have the raw processing power for future games, your 2GB of VRAM will start to limit it's capabilities, which means that you won't be getting the amount of frames that you would be getting if you had more VRAM. You should get either a Titan (not a 690, as it only has 2GB of effective VRAM) or two 7950's or 7970's.

Graphics memory usage

Before we move onwards into the conclusion it is handy to know how much graphics memory the game requires in a preferred resolution. You'll notice that 2GB graphics card are sufficient and that's the number this game has been aiming on. A graphics card with 2 GB of graphics memory minimum is really recommended by us. Should you have less available and run into performance issues, the easiest way out preventing frames from being swapped back and forth in that frame buffer is to select lower quality settings or disable AA levels.


Quote:
Above you can see a wide variety of in-game selectable quality modes @ 2560x1600. We switch in-between the image quality modes (Low to Ultra) to monitor frame buffer utilization. As you can see we are hovering at the 1.5 GB of graphics memory with FXAA enabled starting at High quality mode settings already. Once you increase the quality settings towards Ultra mode you start to reach a turning point where the game almost hits 2 GB of graphics memory. The measurement shown above is fairly similar and applicable for 1920x1080/1200 and 2560x1600. Now not everywhere in the game that much graphics memory is used, but there are some critical points in-game where you will reach or even pass the 2GB in combination with the highest quality modes. If you'd apply an exclusive AA mode like MSAA though graphics card drivers, we have no doubt you'll breach the 2GB threshold. So be careful with that.

Overall the advise is simple enough, make sure you have a graphics card with 2 GB of graphics memory when using High to Ultra image quality modes. Please keep in mind though that memory utilization will vary a bit per level, it's not a very precise thing to measure. As such take these values as an indication, not a precise measurement.

Anyway, 2GB minimum for your graphics card, it is the magic number to find Elizabeth wink.gif

I think you mean $800.

Once again...

I bought a normal 2GB 670 EVGA card. It burnt out. EVGA was out so they shipped me a EVGA 670 GTX 4GB Superclocked card for a free upgrade. So really, I am only investing 350+400, because the card is on sale today, and I help out my credit score because I will use BillMeLater. smile.gif

I pretty much only bleed green and don't think I will be bleeding red anytime soon. Two major manufacturers, HIS and SAPPHIRE, both left bad taste in my mouth. Their RMA process was horrific.

If you want to talk about economics, buying a Titan or a 690 wouldn't be economical what so ever because I have a 670 already and in SLI, the 670's beat either one of those cards in single setup. Not to mention each one of those cards cost the same as a 670 SLI setup.

2 x GTX 670 4GB's is even better.... I think you'll be ready for a few games yet to be released (do not like the word 'future-proofing')..
I say again, do it.
