GTX780 SLI : Any reason not to buy refurbished?

[indranil]

Hi,

 

My PC specs are as follows:

 

MSI MPower Z87 Motherboard

Intel i5 Haswell 4670k processor (cooled by a Corsair H100i)

16GB Corsair DDR3 1666 Mhz RAM

Zotac nVidia GTX780 Graphics Card (reference design)

1 256 GB Samsung 840 PRO SSD

1 120 GB Samsung 840 SSD

1 2 TB Western Digital Black HDD

27" Qnix IPS display (1440p)

1000W Seasonic PSU (80+Platinum)

 

I built my system August last year, and it has served me exceptionally well.

I had planned on upgrading parts of my PC every 12-18 months, and I want to purchase a second graphics card and run the 2 in SLI mode.

 

My questions:

a. Is it possible to SLI a GTX780 with a GTX780Ti, and are there be any caveats I should look out for?

b. I have been looking at some refurbished models at Newegg.com, and they seem to have mostly positive reviews, with a great price! Any reason not to get a refurbished one?

c. Will my reference design card SLI well with either a Direct CU2 or an ACX cooler designed one?

Thank you in advance for all the help!

you cannot SLI a 780 and a 780ti

a. You can't SLI a 780 and 780Ti, unless you make one a PhysX card.

b. As long as you know you're getting what you paid for, why not.

c. Coolers don't matter, one can be cooled by liquid nitrogen and the other can be cooled by a reference cooler and it'd make no difference, SLI doesn't care about coolers.
