Another suggest a GPU for me thread... sigh...

post #1 of 9
Thread Starter 
Ok, so I need a new video card. My gtx 470 died and a replacement from EVGA RMA is coming tomorrow. My video card was the only part I was bringing over from my old build. Everything else from my sig rig is new besides the monitors and video card.

My gtx 470 just isnt up to the job to run both a 30" 2560x1600 + 20" 1200x1600 . It would get up in the 90 degree + range 100% load. I was thinking of getting another 470 and putting them in SLI but that is just too much heat for me.

I will either be going with a 590 gtx hydro copper or a 3gb version gtx 580 with the option of going SLI in the future. What would be better for me? The 3GB VRAM with the single 580 with option to upgrade to SLI 6gb Vram total (3gb shared). Or is it better to go with the dual GPU even though it is total 3gb vram (1.5gb shared). Evga said their 3gb version 580 will be coming out this month.

I am ready to buy, and will be adding another 280 rad if i go with the 590 hydro. Anyone know how they OC? I know stock they are underclocked dual 580 chips. If they OC well you should be able to match 580 sli performance in theory right?

I'll be honest the GTX 590's don't over clock well. I've been actively reading the 590 club thread. The AMD 6990's have a better over clock ratio but nothing to get excited over really. Dual GPU cards just aren't great over clockers in general.

It's more money but two GTX 580 SLI obviously will outperform the GTX 590 dual GPU. A lot of people with higher resolution than 1920x1080p monitors have been eagerly been awaiting on the GTX 580 3GB cards coming out. They will be beastly behemoth cards.

answer for triple monitors
get something with at least 2GB VRAM

either 2x 6950's to unlock (make sure you choose the 2GB Ref models)
or 2x6970's
or 2x 3GB 580's

don't even go 590 unless its a non ref card with beefed up VRM's
its an excellent card with a poor power delivery system that will burn/blow up once you start jacking the volts up to OC to stock 580 clocks

or you could go 6990 if you could afford it

as above from what I've read the 590 will pretty much brick when you just think about ocing it : / 2x580 3gb would probably be the most raw power from a duel gpu setup, but price wise you may find that you get better performance returns on 6970's or better still unlocked 6950's.

the ATI cards also have the advantage of higher vram 2/4gb as standard. which with you pushing so many pixels as you are could become pretty significant.

Im sure your aware of this already, but just in-case your not, when you add 2 1.5gb cards in sli/xfire you still only get 1.5gb of total available video memory, not 3gb. Makes sense if you think about it otherwise all the texture data would have to keep on being transferred between cards in order for them to share the workload.

Ah incorrect statement "probably brick". The cards that have bricked, voltage tweaks were also added. Those over clocked with no voltage added yielded 'black screen' or stopped the stress test or benchmark abruptly.

I could say the same for the AMD 6990 on a review from Legit.com where the AMD 6990 just died after some over voltage OC test. After the same card was brought back down to stock it just died in a test on the reviewers. Go figure. But again, it was because voltage was added.

Voltage tweaks are really not good for any card. If you just over clock without voltage you won't brick the card. That's why I said the 590 didn't over clock that well in proportion to the 6990 which has higher percentages of OC with neither of them with voltage added.

Any OC'er should be aware and should know that adding voltage there is always that chance of burning up your VRM. Risk is part of the scenario.

Thanks for the replies guys. If I go with the 590, it will be the evga hydro... They have a lifetime warranty, so not too worried about it "dying" (evga is pretty good with their warranties even when OC'ing). Right now it seems the I could get a 6990 for a fairly good price, and add a full water block for about $150 more. I would really rather stay with nvidia, but will the 512mb extra vram really make a big improvement?

Psh maybe I should just wait a bit longer for the 3gb 580's... They didnt seem to really show improvements over the 1.5gb 580's until over 1600p resolutions, but I might be adding another 20" in the near future bumping my total res to 4960x1600. I am sure the extra vRAM would be very helpful in that situation.

Hard to decide...

at super high res vram can become an issue, easy enough to check if its a problem on nvidia cards, not so much with ati for some reason it wont let you see ram usage >< If you want to stay green then I would wait for the 3gb versions of the cards, even if 1.5gb is enough for now textures are getting bigger and bigger dont want to end up wishing you had done in a years time

I say going to a single 3GB 580 for the time being should be enough. Can't imagine needing more than that would be necessary. >.<

gtx590 dont oc well,moreover as u know they are 2x underclocked gtx580,
so better u go with gtx580 3gb & put another in future,
gtx580 oc very well
