So i was wondering if any 1 has Radeon HD 7970 GHz Edition with crossfire 2 of them and was i was wondering if i should get 2 of them or get a gtx 690 for 200$ more
i cant seem to find benchmarks for 2 Radeon HD 7970 GHz Edition in crossfire
i also heard that radeon video cards are a lot nicer for rendering/editing stuff i was wondering if anyone could back that up for me

Well performance wise, the GTX 690 is superior. However if you want the most performance for not as much, the 7970's GHZ, its performance is very similar. However if you have $200 more to burn, then go ahead with the 690, as its cooler, more power efficient, and slightly weaker than two GTX 680's in SLI.

Yeah, its the only issue with Nvidia cards that I dislike, as well as Cut down memory interfaces. I like the 7990, because its 6GB, which is really 3GB+3GB, which is great above 1080p. If you haven't noticed in my other posts, I'm sort of an AMD Fanboy :p .

Really, I'd love a pair of 7970's, but when your talking about cooling, and power usage, the 690 is definitely superior.

so a pair of 3gb 7970 in crossfire, you actually get 6gb vram in total that can be used , and not 3? am i getting it right?

Yeah, that was what i always thought, it was just confusing that he said "6GB, which is really 3GB+3GB." Never mind, may be just me reading it wrong

As i see,
Gtx 690 is superior overall with energy/heat efficiency, and performance especially in full hd res. However this card has a price premium.
At higher res 7990/7970 cfx is mostly better, performance wise. And the price of cfx is less compared to gtx 690. However, this comes with a lower energy efficiency. With some driver optimisations and fixes, radeons have potential. Depends though...
I think it comes down to your choice + BigMack70's question earlier: "What do you need the extra GPU power for over a single 7970 GHz edition/680? What games are you wanting to play with this?"

im looking to play everything on maxed while recording it which is why i want the extra power id be recording with fraps or DXtory + id be rendering stuff with them
i also want to make sure my purchase last me at least 2 1/2 years while i have the chance to buy these
iv been hearing a lot of different things for rending stuff that amd is better or nvidia is better and i cant seem to find a solid answer for it
i do know that rendering stuff is mainly put on the PCU and not the GPU

If you have a decent sized case , a proper motherboard and a quality PSU than 7970's will work and at around $800 it a better deal than the $1000+ 690. It all depends on your setup and what games matter to you!

Why buy 2 128gb SSDs when you can buy 256gb one? Generally cheaper too.

The 7970 crossfire is faster than the 690. The ghz editions are faster than that.

From the look of your build, you don't 2 7970z since you are running 1 1080p monitor but its your choice.

I never knew RAID 0 increased the performance of SSDs, I thought it was only for mechanicals.

RAID 0 Improves any performance no matter what the medium is.

It access each drive in parallel, so literally 2x the performance.

SSD Read Speed: 500MB/s ... RAID 0 x2 = 1000 MB/s

Hypothetical Speed of course.
