Hey Guys,

I have to exchange my GTX 680 on account of a coil whine and an overclocking issue. I am now debating on whether or not I want to swap it for a new GTX 680 or a pair of 660 Ti's. They'd be roughly the same price since I bought close to a $600 680. From what I could tell/hear, 660 Ti's in SLI perform up to 50% better than a single 680. Do any of you have any experience with this? And which 660 Ti would you recommend? Thanks!

I have experience with GTX 460 SLI.
SLI is great for a performance jump. Just don't forget that temperatures rise quickly, and your PSU will have a harder time to pump these cards.

I personally would get a 670 right now and save the money to get another 670 in a month, 670 SLI is only 5% worse than the vaunted 690.

If you have to get 660 Ti SLI, make sure you PSU can handle it and your case can cool both adequately with a side panel fan.

If your case have good airflow & a side panel fan: Get MSI PE/OC version of 660Ti(hopefully your PCIE slots are at least 1 inch apart)

If your case have average airflow and no side panel fan: get EVGA 660Ti, those will be louder but won't heat up each other in SLI when stacked ontop of each other.

I would go the 670 SLI route but I'm going to back to school soon so I don't know if I'll be able to afford a second one any time soon lol My case has great airflow so I'm not worried about that at all.

To be honest I would like to know this as well. I'm stuck between Asus 680 Top, and 2 660Tis :X

Personally I would be all over that Asus 680 TOP for its high factory overclock, improved cooler,heavily modified PCB, with an efficient VRM design to produce low temperatures, improved voltage regulation circuitry, much better ChiL controller , specially binned chip and voltage control and monitoring support that you won't find on most other non-reference cards. It looks aggressive to me and indeed is quite a monster let's keep it on the real not only does it violently murder most of AMD cards period it does it without even breaking a sweat do yourself a favor get the Asus 680 TOP you won't regret it :o

if i had the money for either option, i would go for a nice 670 (not stock). can perform as well for a little less cash. that's if someone threw $500 at me.

Another thing I'm considering...670 SLI; If I crunch some numbers I MAY be able to afford it...Worth the extra $200? And I read in some review that even an efficient 600W PSU could handle the 670 SLI config; so I'm pretty sure mine could handle it. What do you guys think?

That would be a question only you could answer would it be worth it that all depends as far as Power supply go nVidia itself recommend 500W for a single 670. Add 170W for SLI & recommended is quality 670W.

For testing conducted for SLI 670, the resulting system consumption for SLI is 433W of which 293W are attributed to the gpu cards.

All points out to a quality 750W being more than enough and a quality 650W might be pushing your luck.

Right, well I do believe my PSU could handle them both. If not, I have an extra 500W laying around that I could always hook up to run one of the cards until I can afford to buy a new PSU :D

I think I am going to go with the 670 SLI as soon as my money gets refunded from the returned 680. Speaking of, has anyone dealt with TigerDirect's return process at all? Is it fast/secure?. Any recommendations on what card to buy?

Not sure i never had to return anything to tigerdirect but for the 670 i would get ASUS GTX 670 Direct CU II or MSI N670 PE 2GD5/OC GTX 670 ;)
