Sapphire 7970 3GB OC Vapor-X vs gtx 670

[dark15240]

actualy have
Cpu 3570k @ 4ghz
8GB ram
mobo msi z77a-gd55
ssd samsung 830 256Gb
760W psu (seasonic X-760)
No case , using the hd4000 graphic
Now I've got money for graphics and looking for something @ 400 euro

I've seen Sapphire Radeon HD 7970 3GB OC Vapor-X
http://www.eprice.it/schede-video-SAPPHIRE/d-4459578
should be 1Ghz + boost

GIGABYTE wind force 3x Gtx 670

and asus GTx 670 Direct Cu II (not TOP)

Until Now I've only used Nvidia graphics but the offer for the 7970 seems good
Does anyone have both of em? is the 7970 much louder ? it get much more hotter?

The REFRENCE is hot and loud if you OC it, yes. Which I'd never get reference if I know I'm overclocking. But a 7970 blows the 680 out of the water in performance. Especially when you put a nice OC on a custom cooler design (Saphire for example) I would recommend a Saphire 7950 because the price/performance is way better then a reference 7970. (Being only 5% slower per clock!) But if money is no object go for the 7970. But if you're OCing, which I recommend get a custom cooler 7970 as even a OCed 7950 Saphire beats a reference 7970 when clock OCed.

So basically:

AMD: Raw power, better in Open CL, better OCer. More Vram then 2GB models, so you can crank up that MSAA eye candy.

Nivida: More refined. Cuda, Physx, adaptive vsync, superior 3D vision. (More stable drivers? Dunno because I've never owned a Nivida card)

So if you really like Nivida's more refined cards, which offer alot of features,and don't want to OC, go Nivida.

If you want pure crushing power the 7970/7950 Custom Cooler models (I prefer Saphire, like the one you picked out there)

Which I'd get the 7950 because even that card outperforms the 680, and you could get a nice case like a HAF. (I would get a case with the money you save, having all those expensive componets sprawled out on my desk would worry me)

That's pretty much my two bits. Sorry I repeated myself a bit, just stressing the 7950 point.

The Vapor-X is actually a GHz Edition, and it outperforms the 670 and 680 on basically anything other than Nvidia-optimized games or softwares that make use of CUDA cores.

Though the 7970 GHz is more power hungry than the two high-end Nvidias; that specific model though, the Vapor-X, I heard is really quiet.

Here are some game benchmarks; the last benchmark is for noise.

+1. Pretty much my rambling compressed into a short and curt answer. Very nice. Even though I'd still say the 7950 is much better for the value the 7970. (And you'd have money for a case!) And 7950 isn't the Ghz editon like the 7970. So those benchmarks aren't realistic.

^I'm sorry I don't seem to understand that last sentence. XD

Is Physx so important ?
I've read in a review that the Cpu does part of calculation also but the frame rate goes down,

Just wondering if i put a nvidia older card in my 4x slot and use 7970 for the monitor can i enable it?Not for else but it will s**k if I buy the 7970 and in about 2 yeas or so will become important
