ASUS GTX 780 Ti vs. ASUS GTX 780 (non-Ti) ROG vs. EVGA GTX 780 Classified (non-Ti) - need to make a decision

post #1 of 6
Thread Starter 
I have the money to buy ASUS GTX 780 Ti (DCII cooling, NOT reference), but not EVGA GTX 780 Ti, at least not for a long while. From what I read, the ASUS card runs cooler (and has a backplate!) and quieter, but has crap customer support and supposedly does not overclock as high as its EVGA counterpart, which overclocks better, has better customer support + step up program, but EVGA fans can get pretty loud even on Classified edition c ards. I also I read in a few threads that ASUS uses chips that are voltage-locked, doesn't it? I do want a high OC, but I am going to stay on air. Is EVGA less voltage-limited? Would that matter if I am to stay on air? How much further would EVGA Superclocked or Classified overclock? What about UEFI/BIOS mods? Could ASUS be unlocked and help me reach higher OC with such mods if I am stay with air cooling? A buddy of mine with EVGA GTX 780 Ti reached 1300Mhz GPU clocks with air. I assume there is little to no chance ASUS GTX 780 Ti could do the same? It does run cooler, so why the heck not... Overall, are ASUS GTX 780 Ti cards CRAP comparing to EVGA ones when it comes to air overclocking???

My other choice is to get cheaper EVGA GTX 780 (non-Ti) Classified, which AFAIK, would OC really well, wouldn't it? What are the chances of reaching GTX 780 Ti speeds with EVGA 780 Classified? Reaching GGTX 780 Ti SPEED is not the same as reaching GTX 780 Ti clocks because in addition to clocks, GTX 780 Ti has more shader processors and etc. That means that GTX 780 clocks would have to surpass GTX 780 Ti clocks for that to happen..

I could also get the ASUS GTX 780 (non-Ti) ROG Edition, which can be hooked to water-cooling that I am not likely to have, but I am sure it allows for higher OC and has some unlocked features?

Generally-speaking, GTX 780 Ti is better than GTX 780, but is ASUS GTX 780 Ti better than EVGA GTX 780 Classified Edition? I am concerned about the whole "locked GPU, voltage" thing people are talking about regarding GTX 780 Ti...

Would my Corsair Gold 850W PSU be good enough to OC either of the cards I listed?

I don't know which Corsair PSU you have exactly, but it is plenty for this.

 

I recommend getting the card from Amazon.com so that you won't have to worry about ASUS support if that becomes a necessity.

 

So, I say that if you can afford the 780 Ti DirectCU II, then go for it! I bet that you won't feel the need to overclock it!

Almost all 780 Ti cards are locked to 1.187v maximum out of the box.

With a custom bios, 1.212v becomes your limit.

With 1.212v unlocked, almost all 780 Ti will do 1200 mhz or better. In fact, most do 1200 mhz with 1.187v.

1200 mhz in a 780 Ti is equal to 1350-1375 mhz out of a 780.

And your psu is more than enough.

I run a corasir 850w psu with no problems with my power hungry overclocked 480 SLi. I just installed an Asus gtx780 DCII. Pretty much the same performance on some games (more on others like Crysis 3) but less electricity usage.

I was also thinking of maybe getting a non-Ti but then getting $250 worth of water-cooling equipment for CPU and GPU, but my case is awfully small for that I think - Rosewill Challenger Black Gaming ATX Mid-Tower Case. That ASUS ROG GTX 780 with pre-made water-cooling blocks and plates could probably go far with a decent rad and pump. What would be an excellent pump and rad for this card? Can water=cooling and fans be used at the same time on that card? That would make it uber-cool, uber-nice for OC!

My non-Ti idles from 27-30c at default 33% fan and maxes out at 48-54c with fan at 80%. The cooler does a good job.
