Hey, I need a bit of help here, I bought a gtx 670 today & I already had a gtx 570, I linked them both up & installed them into my pc. The problem is, that seemingly, 1 card alone gives me more performance than both combined (via the nvidia control panel), what's even worse is that the performance isn't all that good (i.e. 30 fps in Batman Arkham City, 25-40 in JC2 benchmark). The drivers are up to date & my PSU is 520w, so I really doubt it's that. Has anyone got any ideas what may cause this?

two different series cards, you dun goofd. Maybe if they were the same PCB you could SLI but they're two different generation cards. Sell the 570.

SLI does not always equal double performance. Some cards will have terrible scaling, plus the game may not have support for scaling and result in microstutter.

What about 2 670s?

Basium · « **Reply #6 on:** October 12, 2012, 02:07:12 PM »

how much you bought GTX670?

Blaze · « **Reply #7 on:** October 12, 2012, 02:10:34 PM »

two 670's would be just under double performance.

do you really need SLI 670's though?

I guess I'm just trying to prepare myself for GTA V is all, want to make it look good & run it proper. I don't really feel the need for it atm, but since I have some disposable income, I can save up for it.

at full load one 670 is approx. 250w, so two 670's will draw approx 500w, Probably need to upgrade that aswell.

You still won't be able to run it if they port it just as badly again as they did with IV.

Yes, I need it

I'm planing to buy a new pc, and new video card would be great addition, wouldn't have to spend money on it!
Also, I was going to call You today, but somehow I forgot it ;/

Had the same problem with 2core GPU few years ago. Only one core was working.
