gtx 980 sli or gtx titan z

Hello all im not sure what gpu to get this is my specs:

asus maximus extreme iv

2600k@4.2 ghz

16gb ddr3 2133mhz

1tb hdd

3xb2430l in nvidia surround

i would like to game at the very best fps

any help would be great

2x980 easily

980s

@MonsieurX: how come you say 980s?

980s are faster unless they run out of VRAM. They're also cheaper.

Thats why:

Best bang for buck are two GTX 970s in SLI.

The 980s are barely stronger and to SLI them would cost over 460USD more.

I agree, for 4K display the best bang for your buck would be 4x 970s not 4x 980s

980's without question. Titan Z is fail unless you can get it Ultra cheap.

@klunt_bumskrint: so you guys are saying sli 980? even at 5760x1080?

You should wait for 8GB 980s. They're just around the corner.

Either this ^ or 2-4 way SLI 970s.

Hands down if 970s going to get 8Gb version as well.

If I were you I would look in to upgrading your CPU as well. I just went from a 3770k at 4.5 to a 5960X at 4.2 and the difference is night and day. The 5930K and 5820k are also great options, especially if you are only gaming or only plan on 2 GPU's. If you don't want to jump into X99 yet the 4770k and 4790k also do well. But multiplat console ports are starting to use more CPU power and that may become a bottleneck for you.

Oh and don't ever consider buying a Titan Z. And I'm an Nvidia fanboy.

two 980s over the titan. but two 970s makes more sense... you're throwing money away otherwise for small gains.
