I want to replace my 7970 with NVIDIA equivalent or better

[marmoro]

Hi folks,

These are my rig specs:

ASUS P8B75M (I know it sucks, will replace with upcoming mobos)
Intel i5 2600k @ 3.4Ghz-3.8Ghz stock clocks
8GB DDR3 RAM
HIS 7970 IceQ X² 3GB GDDR5 Ghz Edition
BENQ XL2720Z V2 @ 1920x1080 120hz


The reason I want to switch to Nvidia is that I want to get advantage of Nvidia 3D vision and I want to get consistent 120fps on 1920x1080 without eye-candy

I've never owned a desktop Nvidia card so I'm having a hard time choosing which one:

GTX 770: http://www.newegg.com/Product/Produc...82E16814125463
GTX 780: http://www.newegg.com/Product/Produc...82E16814125488
GTX 780ti: http://www.newegg.com/Product/Produc...82E16814125493

Assuming you know how to overclock or have a GHZ 7970:

NV equivalent is a GTX 680 or GTX 770 but if you want significant improvement, the only card that is significantly faster is the GTX 780 ti (or TITAN but it's too costly for pure gaming purposes). The non-ti version GTX 780 is only a ~20% upgrade over the 7970 GHz: http://www.techpowerup.com/reviews/NVIDIA/GeForce_GTX_780/26.html

A word about 120Hz if you are trying to consistently lock your framerate to 120fps:

You should also turn graphics settings way down to hit 120 fps in most modern games. A MINIMUM 120fps is a LOT to ask of one GPU at 1080p, even if your CPU does not bottleneck you. Look at reviews, how many current games can a GTX 780 ti drive to 120 fps at 1080p with high settings? Only the games built on old engines. And that's with stronger CPUs than what you've got.

But if you are ok with dipping below 120 fps then you can use weaker GPUs with fewer problems.

Nothing NV have is a worthwhile upgrade over a 7970 level of performance except for the 780ti, so I agree with BC above.

However, don't be in a hurry to spend so much $$ since next-gen Maxwell is not too far away.

I ran Heaven Benchmark several times with minor OC to my 7970 but then the total score highly went up (like 20 points more).

I wonder if its possible to SLI a GK110 with a Maxwell.

It is not possible,

nope

GTX770 is somewhat faster than the 7970 however the 7970GHz or R9 280X is pretty much on par with the 770, and right now the price of those has plunged significantly.

Also as someone who had 3D Vision: it is not worth it. Few games really support it, you often need to find fixes yourself and usually the 3D Vision monitors are TN panels. Yes they are fast, but I'm not looking back now that I switched to a 2560x1440 IPS panels.

I have the 3D vision glasses, I tried it out and it just wasn't for me. I got a 3D vision 2 monitor for the 144hz and the low persistence mode not the 3D and at the time the workaround to enable it required the glasses (or driver hacks) so I ended up buying them to use that. While the effect is nice it wasn't exactly flawless in a lot of games and it was fatiguing on the eyes. I have kind of learnt my lesson, I have gone through eyefinity, surround and 3D vision and in the end I determined I care about 3 things - refresh rate primarily, secondly resolution/pixel density, third colour quality in that order.
