For the most part, I didn't need to use AA in any games. I didn't even use FXAA. If I had performance to spare I could still use it AA though. It's just, in games like Tomb Raider and Metro Last Light, the only real AA was Super Sampling which just crapped on them, but those settings are pretty much like the "uber sampling" found on Witcher 2 that pretty much craps on everything!

When it came to BF3, I ran 1440p, everything maxed with 4 x MSAA. No problems.
Skyrim with the "Graphical Essentials" collection and few other visual mods ran with 0 problems.
Borderlands 2 with everything maxed ran with 0 problems, except Physx would cause the fps to dip here and there if a crap ton of stuff was happening all the time.


Another benefit of SLI 670's? When you need the power, you can SLI them. When you're playing a game like Batman/Borderlands/Metro where 1 670 is enough, you can dedicate the other SLI as a Physx card.

I'd go SLI if I were you. It just sucks that the 670's prices haven't fallen as they should have....

So are you keeping one of your 670s for Physx?

post #3133 of 3566
I agree.. I'm still on 670's SLI @1600P. No issues for me at all either. So what if I I'm lowering AA, still looks amazing at 1600P in my opinion.

Correct me if I'm wrong, but I believe Nvidia doesn't allow SLI configurations between GPU's that have different amounts of VRAM. You'd assume they'd just run using the lowest common denominator (2gb) but I actually don't think that's the case.


Example A

Example B

In both cases, people were complaining that they had a 4gb 680 and a 2gb 680 and they couldn't access SLI.

From Nvidia's FAQ
Quote:
When purchasing a second graphics card, you should try to match the memory size so that you are ensured full value and performance from your purchase. However, while it is not recommended, NVIDIA does offer the flexibility to run graphics cards with different sized memory by using CoolBits. Using CoolBits (value set to 18), you can force both of the cards to use the lower of the two memory sizes and operate them together in SLI mode. When dissimilar memory sizes are enabled to work together using CoolBits, the effective memory size for each card becomes the smaller of the memory sizes.

Also, in reference to the 4gb versions...Here's a quote from the 4gb review of the Palit Jetstream 680
Quote:
The 4GB -- Realistically there was not one game that we tested that could benefit from the two extra GB's of graphics memory. Even at 2560x1600 (which is a massive 4 Mpixels resolution) there was just no measurable difference.

Keeping my 670 FTW as a folding/physx card

Mainly looking forward to using my 670 as a dedicated physx card for Batman Origins (came with the 780)

My 780 and 670 are folding away right now quite happily smile.gif

folding at about 170k ppd right now!!!!

Oddly enough, even though Nvidia SLI is the best when compared to CFX, I still thought that my single 780 was smoother or something. I wasn't expecting it or anything, but when I ran the Valley 1.0 benchmark, I scored much worse than SLI 670's, but it just seemed more fluid that I've ever seen it before.

That said, SLI 670's were still a great match, I was just so put off by my lackluster Gigabyte 670. If I had found a second 670 FTW for a reasonable price, I wouldn't have needed to go for the 780.

Nice, our HFMs look pretty similar right now.  ;)

 

What clock speed / voltage are you at for 170k on the 7811?

I owned 3 different 670s all at different times  they were all great. 1 Windforce, 1 Twin Frozr and one stock with 4GB...

 

I sometimes wonder if I should have gone with the 670 SLI route as well.

Honestly, with MSI, I just moved the voltage up 3/4ths of the way up, then 1202mhz on the core and like -500mhz on the memory tongue.gif

Never really understood the voltage part of the keplar series, always seemed to do its own thing versus what we were used to with Fermi
