Hi there guys,

I bought the "780Ti" today based on few suggestions by you for my PC upgrade :)
I've previously asked those 2 questions:
1. Does PCIx3 GPU work on PCIx2 slot, since my current motherboard doesn't have any PCI3 slots
answer : Yes it works fine ! no problem at all.
2. Do I need to upgrade my PSU when I install my new 780Ti into my motherboard as I currently have a Xigmatek 700W
answer : No Xigmatek 700W would do okay with the new GPU (780Ti)

So is having this specific PC build :

CPU : Intel i7 2600
Motherboard : Gigabyte Z68X-UD3P
Memory : 8 GB Corsair DDR3 1600mhz XMS3
Hard Drive / SSD : 2 TB S-ATA III 6Gb/s / SanDisk Extreme SSD 120 GB
Graphics Card : Nvidia GeForce GTX 570 1,280MB
Optical Drive : 22x DVD+-RW DL S-ATA
PSU : 700W Xigmatek
Monitors - 2 x 22" IPS LG

and adding a 780Ti ... I think of keeping my 570 since its pointless to sell on internet ... and instead I will use it for my 2nd monitor to ease off the performance for 780Ti so that its working to its full potential when it comes to gaming.

But the questions is -- since I want to use both graphic cards with my current motherboard would that 700W Xigmatek be powerful enough?? or do I need to upgrade it..

I personally think that it might not be enough plzz help ! Thank you.

While I agree the 780 Ti isn't as good price/performance, it is much more than a few hairs better, especially at resolutions like 1440p and up.

OP, like the others stated, don't use the 570 for the second screen, the 780 Ti is more than capable of doing that, and you won't see any performance decrease. Your power supply would be more than capable of powering that, as the 570 would be using minimal amounts of power to draw a single, non-gaming screen, but like I said, isn't worth it.

Jeremy, the 570 as a PhysX card would be pointless with a 780 Ti main card. Dedicated PhysX cards are meant for weaker GPUs, or AMD setups that don't have strong CPUs. There wouldn't be any noticeable performance difference between the 780 Ti by itself or...

you cant run both gpu with that psu and there is no point of doing that. running dual monitors on 780ti will be a piece of cake

I agree with the two posts above me. You do NOT need a Ti version of the 780 though, price to performance is not as good, and the Ti is only a couple of hairs ahead of the 780 in plain performance, there's really no need to spend the extra money on it as it will not quantify what you would gain in performance.

Which specific xigmatek power supply do you have ? And I agree that running a second card for a second monitor is kind of a waste, BUT you could use it as a physx only card, and see some pretty good performance increases in some games, depending on your power supply of course :)

The most important number in that article, which is minimum FPS, shows minimal performance improvement, and in two cases decreased performance. Maximum FPS is a pointless number completely. What matters the most is frame time variance and minimum frame rates, followed by average frame rate.

You also have to consider that not many games actually employ PhysX, let alone have enough implemented for it to take a toll on a 780 Ti.

Okay fine so use the 780Ti as main and probably sell the 570 then ... =) I mean since I dont need it and btw isnt the 780Ti great in the long run though ? its has 25 % more CUDA cores and its generally like a buffed version of the 780 if you compare them both. I mean the difference of prices for me .. is £85 - 100. 780 -> ~£400 / 780Ti £500 :? Plus I do really use up my GPU since I work on 2 monitors all the time even when I am gaming.

Yeah, the 780 Ti is a great improvement over the 780. It's not as big of a performance jump for the money, but is still definitely a good improvement, and much more than the 'few hairs of improvement' the other guy said lol

But yeah, that sounds like a plan :) The 570 is a decent budget card for todays builds. Will still get you medium/high at 1080p, so someone will buy it up as long as you price it right :p
