Upgrading question. HD7970 Crossfired or GTx 690? - Page 2

post #11 of 22
No it was also 2 cards I believe. What I know is that the AMD cards were stuttering pretty bad single and dual card. When I updated the drivers, it fixed the stuttering.

That's good to know.

But what about this?
http://www.computerbase.de/artikel/grafikkarten/2013/test-17-grafikkarten-im-vergleich/7/

That's AMD cards using Catakyst 13.2 beta 4 (latest right?) and nVidia cards using 313.96 beta. (though 314.07 is out)

If you have a case and motherboard that permit you to put two cards with a decent gap in between (at least one free slot between them, preferably more) then go with the 7790.

If not, I'd seriously advise the 690 (or whatever the current dual-gpu AMD card is), otherwise you're going to end up driving yourself nuts for a while trying to get the top card to cool properly, then eventually you'll drop a ton of cash watercooling them.

what about the just released Geforce Titan? if you are considering a gtx690, that means you have the money. a single card is always the least problematic, right? it would be about 60% faster than a GTX680. yes, not the same as a GTX690, of course, but you probably will "feel" the same FPS.

Neither do I. just look at the graphs. the 7970 is showing a lot of frame latencies. GTX680 is much smoother.

Not all micro stuttering has been fixed. Single-GPU microstuttering has been greatly reduced on DX9 games.
A new video memory manager is supposed to be released to fix microstuttering amongst DX10 and DX11 games.
Dual-GPU microstuttering exists in both AMD & Nvidia, it's supposedly worse on AMD tho, IDK if the newest AMD drivers affected dual GPU's in anyway.
The GTX 690 is two scaled down 680's put in SLI, since the 7970 is the direct competitor with 680 trading blows with it, the 7970 in Crossfire should beat 690, especially when overclocked.
I'm not sure if a 700W PSU would be enough for oc'd 3570k + 2 oc'd 7970's, might want for confirmation on that one.
Not bad

I'm with skorpian. I would reccomend a 900-950w psu
