just got a 780ti super-clocked w/ the acx cooler. began to over-clock and from tests so far I am stable at about 1155/1775. I'm using afterburner instead of precision just because I like afterburner better. But that makes my clocks at +149/+50 on afterburner. Voltage is at +75, I think thats 1.175 but I'm not sure, maybe 1.750. My question is being that I still have the stock BIOS, is this acceptable or should I be able to reach higher clocks? Again this is still the stock BIOS.

There isn't really a guaranteed amount that the card can be overclocked. If they could guarantee it would clock at a certain speed, they would rate it for that speed, clock it there, and sell it at a premium (which is essentially what they do with the superclocked version vs the stock card).
Well seeing other's valley and furmark scores I will have to update the bios. and I've confirmed the highest voltage I get in gaming is 1.175. But what your saying is the superclocked card already comes at a stable high overclock? Should I take it back and just get the ti w/ acx cooler or MSI ti since I like afterburner and just overclock it from stock.

your fine you just need more voltage. there is no reason you can't run the max stock 1.212v that is allowed in afterburner and precision. if you want you can use nvflash to put a skynet bios onto your card which will unlock a higher power target and some more voltage.

there is where you want to go for your questions, it also has team skynets bios for your model so you can get the most out of it , though if you really want to overclock high you should get an evga classified ti. my regular 780 classified is running a skynet bios and i push 1300mhz@1.212v as my 24/7 stable gaming overclock when i need the extra boost, but I've gone higher just for fun, 1375mhz@1.275v but temps go up quick with that amount of voltage. I've also got a 3349 score on valley extreme hd running 1350mhz on the core. but i have really crappy memory as i have trouble getting to 1700mhz unless i add some memory voltage via the classified voltage tool.

Funny you should mention that as since I woke up today thats what I have been doing. I flashed to the skynet bios and switched to percision as I couldnt get afterburner to raise voltage or use custom fan profile. I began to over clock and was able to reach an offset of +254(1300mhz) on the core. I gradually increased up to +299 by inciments of +13 until i crashed to desktop. Then lowered it back down and rounded it off at 1300mhz which is the +254 offset. Now I havent tested on game yet and was wondering if I should even mess with the memory clock on this card. 3500 is well above what I was working with on my 7950's haha. My valley score for 1300(valley registered it as 1299) is 3310 79.1 fps.
Now on the subject of the classified. I looked at them but I like to buy from microcenter and they do not carry the classified. I was thinking of sli'ing this ti instead, once I get my asus 1440p monitor.
Update: I ran valley on loop and saw artifacting at 1300 so i dropped it to 1293(+247 offset). I ran that on loop for a lil saw no artifacting. Benchmark came in at 3297 78.8 fps.

well your going great for a standard acx model if you can get to 1300mhz so that sweet. if you want a higher valley score it will react well to higher memory clocks. but if your on a single 1080/1440p monitor a memory overclock "might" add one fps. the memory has plenty of bandwidth anyways so you don't need to overclock it.
i would let valley or heaven loop for about a half hour or so to check stability. keep an eye on temps as you don't want to go over 80c on the core, also on your card i don't believe you can read vrm temps either and you don't want those going over 85c for long.
i had the msi 7950 tf3 also before, though i was voltage locked at 1.25v since it was a boost edition and there was nothing i could do about it. but i was able to sit at 1175mhz core 1575mhz memory.

Ok then I won't touch the memory. at least for now. I read about a way to pump voltage more but I'm going to leave it here for now especially since i plan on sli. I just played arma for about 90-120 minutes with no hickups so I'm quite pleased. The single card setup overclocked is running better than the crossfire 7950 overclocked on that game and its one of my favs. I think I'm good to go tho. Thank you for the responses everyone.
