moving from AMD to Nvidia

Hi all,

I need a little advice regarding the modification of my rig.

Here is my config:

i7 3930
ASUS mobo p9 x79

Firepro w8000

32 g Ram Corsair dominator 1866

PSU 1000W Silverstone Strider Plus, Full Modular

Phantom 410 - NZXT case

Corsair H100i Hydro Series CPU Cooler

5 noctua fans in total

I use c4d, AE, Premir, PS.

I tried octane and I decided to make my move and leave AMD (the firepro w8000 is really good, but it cannot compete with the support of Nvidia)

I am planning to buy 2 GTX 780 Ti for start.

1.The question is, is there anything else I should change in my rig, like PSU?

2. If I need a bigger PSU what do you recommend, bigger PSU or GPU PSU?

3. Is gtx 780 Ti is good enough to handle smooth video editing like w8000? I think AE is not effected, it is only CPU and RAM depended.

4. Is there anything I should be aware of?

5. has anyone come from a similar GPU background (firepro AMD), what is your view? Worth the shift?

All advice is welcome!

Thank you,

Misi

NVIDIA GeForce GTX 780 Ti is very good for OR only but it may not able to accelerate in video editor except AMD-ATi FirePro or NVIDIA Quadro. ;)

Better solution is GTX 780 non-Ti 6GB, 2 or more videocards can get the scale of performance but not VRAM (GTX 780x1 or x2 or x4... have only max 6GB). :)

PSU is very important for high-end videocard:
eg: Single GTX 780 -> PSU 650W
2x GTX 780 -> PSU 1000W
...

Thank you!:)

I would like to go for this:

http://www.amazon.co.uk/Strix-Gtx780-Oc ... 780+ti+6gb

and a GTX 780 Ti 3gb

OR

http://www.ebay.co.uk/itm/151462353221? ... EBIDX%3AIT

Is it worth investing into this one plus the GTX 780 Ti 6 gb?

Ram should be a issue which is related with your needs. Big ram is always good if you need big and many textures, big render outputs. You can test your scenes with demo version and you can make better decision about ram.
But 780/780Ti looks best solution mostly.

Hi misi, may a important info:
The VRAM of GPU is not added if you have a 3 GB and a 6 GB card.
You can use only 3 GB if you render with both cards but you can switch off the 3 GB card and have the 6 GB card alone to render.
If you work with big scenes, lot of high res textures and hit the 3 GB limit you cant render at all.
The GTX 780Ti is faster but the GTX 780 6 GB leave more room, so it depends on your workflow and needs.

Cheers, mib

Thank you again!

It seems that the Titans are the best solution to work without compromising the work flow.

Do you think I am safe with the 1000 w PSU and two cards?

I leave the conversation open just yet as I am very curious what people say regarding rest of my questions.

Every opinion matters!:)

Thanks again!
