Going for a new 6core setup. Should i upgrade my GPU from a 570 or just get another and SLI?

on this graph i would say that a fairer comparison would be 670 sc @ 967/6208 v Ghz 1050/6000

No that's not a 'fair' comparison. It's an out the box BIOS overclock (over a stock 7970) vs a stock card.

If you want a fair comparison of that nature then you need to compare against a stock 7970.
 
it is the SuperClocked edition Rusty, so it is partially a fair comparison in terms of FPS results... however I paid less than £280 for my SC card and the cheapest I can find a 7970 ghz edition is £390... even £299 for a standard EVGA one, in SLI you are talking £180 price difference when they will both fully OC to within a few FPS of each other

D'oh!

Did wonder what the SC was referring to. Still think a fairer comparison is the overclocked variant of that card!
 
either way - £80ish price difference makes it very hard to justify the 2FPS advantage it has at stock settings! doesn't really matter what % it is faster if they are both mid 40's but one is £6.87 per FPS and the other is £8 per FPS

add in that the ghz edition is also pretty much maxed out on memory OC where as the 670 has room to add another 400+ mhz to memory as well (which if you compare the lightning 7970 to the ghz 7970 that seems to be where most of the extra FPS gain is coming from)

if you are comparing 680 to 7970 then it's a fairer fight in terms of price per FPS, but the 670 just seems to stomp all over everything else out near the top end

+1

slightly off topic
andybird123 you were also right about the difference PCIe 3 made with multi monitor, multi GPUs at high resolutions and settings.
 
Thanks for the input guys. Been with nvidia for years but tempted to go the extra mile to try the 7970. Love to overclock so feel I would get more out of the card. Btw saw the exact same model as my card finish on 160 on a populour auction site today. So based on that will only cost me £180-200ish to change.
Found an XFX radeon HD 7970 black edition on another website for £346 including postage.

Some reading for you http://www.overclock.net/t/1243717/gtx-570-sli-or-one-gtx-680

My 7970 in bf3 uses 1.45gig @ 1080 with 2xAA, sbao and terrain detail set to high, all rest on ultra.

Whats your budget if you were to buy a new single card?

Keep in mind just because your GPU is using 1.45 gig it doesn't NEED all of that memory. Some of that is more than likely cached memory to avoid it having to load it back off the disk. This was discussed in great length in other topics on here :P

And I had a 570 for a while and I only really hit vram limits with a heavily modded Skyrim. Skyrim is much happier now with the 1.5gb on my 580 ^_^
 
I'd estimate around £350.

Thanks for that topic mate, certainly changed my view. Thinking about going for a 680. Or possibly a switch to AMD.

It doesn't matter what game you play or what resolution you play it. 2 gtx 570's will still be faster than any single card.

Vram is not as important as a lot of people think it is.

I'd go for whatever option is the cheapest.

I've never run SLI before, heard there can be problems running some games? + extra heat generated in case etc. Always been very wary of it.

670s and 680s overclock themselves anyway, so insisting on "stock" settings doesn't make any sense.

I've had SLI before and no problems at all, you forget that you have 2 cards instead of one after a while. As for the extra heat, with a decent case its negligible. I didn't see any increase in cpu temps with the second card. The top card will run hotter, depends on how much spacing you have between your 2 pci-e slots.

Saying that 670 and 680 overclock themselves doesn't make any sense.

Saying you can't have a stock comparison doesn't make any sense.

Then again, this is coming from the same person who judged driver problems overall by the last week of posts in the OcUK forums only so I probably shouldn't be surprised by comments like that. :(

Using MSAA in BF3 is pretty much pointless, whilst hammering your Vram and performance.

MSAA doesn't work anymore, on new engines it is simply broken.... It's time to move on and embrace our new FXAA, TSAA, TXAA etc etc overlords I'm afraid.

Uhm, they do clock themselves, and depending on the silicon quality you could end up with a card thats 5-8% slower out of the box and at stock than the next man even though you've paid exactly the same money. You can't look at someones stock settings and depend on yours performing the same.

I really don't like how NV and now AMD have gone with this auto clocking system they have on their newer cards.

checked again yesterday and it actually used upto 1580mb
and if you have less vram and the things starts having to load off disk then that surely will slow things down? loading even off ssd, again surely loading off memory is very much quicker

this simply isn't true

BF3 on ultra settings @1080p won't run smoothly on 570SLI but it will on a single 670, been there, tried it, returned the cards for something better

in your opinion

in my opinion FXAA is a tawdry blurry mess of a bandaid for cards not good enough and owners too cheap to buy hardware to run the game properly
