Hey everyone hope you all are having a great day. Now I have almost everything for my new PC except my GPU. I've come down to two choices.
First choice: Sapphire 7970 Vapor X Edition 6gb 384 bit (single gpu) http://www.newegg.com/Product/Product.aspx?Item=N82E16814202005&Tpk=7970%206gb
Second choice: EVGA Geforce GTX 660 Ti FTW 2gb 192- bit (SLI) http://www.newegg.com/Product/Product.aspx?Item=N82E16814130837
I will be gaming on triple monitors. I want to know what will give me the best performance between the two?
If anyone can answer this that will be great! Also please justify your answer! Thank you so much!
erm.... 6 gigs of vram is probably immense overkill, but it will blow the 660ti out of the water....
Triple monitors = pick up a 7970 Ghz Edition. It's the fastest single GPU on the market, battling with the GTX 680. But since you'll be on 3 monitors, the 7970 Ghz is a better choice
They still make em buddy i just posted a link to them. Abstrakt any reason why it has better performance. Also would two 660 Ti out perform the single 7970 ghz edition?
exactly what the 7970 he posted is. it's a 7970 ghz edition w/ 6gb of gddr5
nope. and not all games suport sli. if your doing eyefinity, you need loads of vram
this is really the only situation i'd reccomend that card.....
Hmmmmm ok aight thanks Commissar. Anyone else have a say on this?
i'd like to see whut some of the more experienced members hav to say bout this
yeah mee too hahaahah cause i got a couple friend who do special effects they say for overall performance and price 660 Ti wins here. But for single GPU 7970 all the way
AMD cards are known to have better performance at higher resolutions (above 1080p), especially that card with 6GB. It'll run eyefinity like a champ. Even two 660 Ti's wouldn't be able to compete, especially since you're running 3 monitors
2x 660ti would be aboot.... the same price.... maybe even more....
your going to get alot more performance from the 7970 ghz w/6g vram than the 660ti.
in sli, they don't share vram, and eyefinity is reall vram hungry, so with dual 660ti, it would be 3g vram for ~$640. with the ghz edition, you get 6g vram for $600, and it's alot less power hungry.
for your freinds, it's a little different. they use CUDA accelerated programs, most likely, so the nvidia helps them. or, they could be fanboys.... either case, your probably better off with the 7970. whether or not you need 6g ov vram remains to be seen.
Well for the 660 Ti its about a 60 dollars cheaper, than the 7970. They are a bit biased towards Nvidia Cards but i see the argument that you are making. I think for the extra 60 dollars im getting a lot more Vram and perforamnce than the 660 TI in SLI. I think i may go with the 7970.. But im free to other opininon if any otehr members would like to join in the conversation!
If are running programs that benifit from Cuda get it. If you plan on running a single monitor at a high resolution then SLI would probably yeild better results. The SLI config will more then likely outlast the 7970 in longevity, but adding another 7970 will cure that problem. If you want to do 3D get nvidia. If you mostly play games that are nvidia supported (tesselation etc) the SLI config will be more benifital.
I personally would buy a good gtx680 or 7970. Not a low end SLI config. Better off buying a single 660 ti. Seeing what doesnt run well with it, and adding another when neccessary.
Having read that you want to do 3 monitor gaming. A 7970 is the much better choice.
Also, VRAM does compound sort of in SLI. I read an analogy about it once:
A man (CPU) has 2 arms (VRAM). When 2 men are put together to do a task, there are 4 arms in total but it is still 2 arms per man. The task will be done faster, of course.
So even though it doesnt make you have 4GB of VRAM, it does make certain games that benifit from SLI run much smoother with the extra on hand VRAM
All right well that decides i think ill go for the 7970! Thanks so much guys i really appreciate i will post up some pics when im done building it :D once again thank you!
