NVIDIA 780 Ti Announced (18/10/13)

I'm all for being proved wrong but I can't see it completely irradicating the Titan from the top tier card. For one the Ti will almost definitely not have 6GBVRAM and I doubt it will have the remainder of the CUDA cores open. Logic dictates at the very most this will be an overclocked Titan with 3 to 4.5GB. Interestingly though he made the point of saying it's also the quietest card...(?) Overclocking Titans on air in SLI is like trying to blow on a lava flow, so really want to see what this card is.

lol at circa 1.4V you nutter. Hate to think the draw on Quad SLi on a heavily clocked system. Think my 1500W Enermax would definitely need a helping hand.

Same for me.

I can see the 780Ti being an addition but not a replacement. I can see 780 cores (2304) with 6GB ov VRAM and much higher clocks. The Titan/780 can pass a stock 690 with a little effort and all Nvidia have to do is clock the nuts off it and claim it as the fastest card they have ever made...

I am probably a mile off but speculation is great.
 
I'm almost beginning to see a well priced Titan (if I can find one) as a good option for my single card solution. When you factor in that I'd have to upgrade my PSU to get SLI then it almost makes sense to get the faster card.
 
Yeah, luckily I'm having a desk made for me which will take a week so not like I could use my PC at the moment anyway. Getting withdrawal symptoms though :(
Brand new, EVGA looks best value but basing this purely on base clock lol. That's the second thing you've mentioned selling me today!

I'd say for 780GTX and upward a decent 1200W is the minimum I'd use for two cards. Especially in an overclocked system.

?

850w would be fine for two 780's without overclocking though. They only have a 250w tpd each so that leaves 350w for the rest of the system which is more than enough.

If you are going to be overlcocking a lot then I agree you will need more but 850w would be fine for 2 780's I reckon.
 
I don't understand why people are saying you need more than 850w for overclocked 780s in SLI. The [H]ardOCP link I pasted above clearly shows that an i7-3770K @ 4.8ghz with a 780 Lightning and a huge overclock "only" drew 458w at full load. Surely another Lightning cannot possibly draw 400w+ by itself?

Not sure if this is going off-topic though.
 
I guess if I was running 780 SLI I wouldn't bother over clocking, so I now realise how pointless it would be me getting classifieds or Lightnings having said that. I guess I'd wan't the fastest stock one which I'm sure is the Zotac Amp one, but I've never heard of that brand before.
 
The problem is having headroom for adding more voltage. Some peeps want to fire in quite a bit more volts and this is where the minimum spec goes completely out the window. Chuck in a heavily volted CPU and again, the recommended specs are pffft :D

If you intend to keep within the cards limits, sure thing on the manufacturers spec but if you intend to have some fun, get a bigger PSU (more is better than less).

I know with 680 Lightnings in SLI and a reasonably clocked 3930K, 750W was more than enough but if I went for a reasonable overclock, it would easily pass that 750w

I am far from knowing much about PSU's but my multi meter doesnt lie :)

Fine is a broad definition. It'll work yes, but you're putting your PSU very near if not on it's maximum efficiency in some cases, and add an overclock to that and it's possibly going to be on a very thin line dependant on various components. I normally want at least 200-250W spare after you account the rest of the system.

Why do that when for an extra few quid you can put your PSU at a much lower load? Always go above and beyond recommendations TBH.

Extra few quid lol, the 1200w PSU's you're recommending are £200+

The PSU is the most important part of your system but 1200w is overkill for 2 cards unless you've got them pushing mad volts. Could always help in the future though, but cards power requirements should keep getting lower as the nm drops to 20.
 
Depends. Add some reasonable custom watercooling, a few HDDs and an overclock on the CPU and 850W with two of those cards...

Feel free to carry on but I know what I'd be doing :)

Just to clarify I'm aware that it would all be within tolerance but 850 is a bare minimum and I don't see the point in spending that much on GPUs just to put a PSU within 10-15% of it's maximum efficiency.

I'll have a look when I get in to see how much power I draw on my system with a 780 with 1.212V and at 1250 with my 3770K at 4.7. Not massive overclocks but substantial enough. I've got one of those reader thingy-ma-bobs :D.
