Hi

I'm thinkin about buying a new graphic card. Until yesterday I was pretty sure I'd buy 5870 but I started considering buying 2x GTX460 (price would be a little bigger). Whad do you think about it?

As far as I know, GTX460 in sli will be better in dx11, though such configuration would be hot and loud as hell.

It would be hotter and louder, but also faster maybe by about 20%.

Up to you whether its worth it.

2x GTX460s are faster than a GTX480, which is about 15% faster than a 5870.


I think in terms of SLi scaling, it almost approaches the 5970, which performs equal to two 5850s in Xfire. So I'd say in a best case scenario, you can see 40-50% fps improvement over the 5870.

The GTX 460 can also OC to a significantly higher degree than the HD5870.

Really? 2x GTX460 would be that fast? Well maybe temperature and noise are not that bad after all...

Yup, that is what the review says.

Individual temperature will be lower than the 5870, but total heat output and energy consumption will be a good deal higher than the 5870.

But performance will also be much higher.

Wow even the max temperature is lower than 5870. Although power-draw is bigger and it's a little louder. Maybe someone here have such configuration (sli) and can tell if the noise is annoying or it's easy to put up with?

Right. Forgot its Individual temperature.

The actual temperature the GPU core(s) is running at is a secondary consideration. What will matter more from a practical standpoint is heat output and that is directly related to the amount of power used by the card(s).

sli/crossfire troubles not worthed for such small gain in my opinion. Always better to go single card (whether it will be ATI or nVidia)

Go for a 5870 and then you can add second (or 470GTX and later add second)

by buying 2 x460 you limit yourself . But its up to you. 460 is greatest nVidia card at the moment

If single it would only be 5870. 470 is slower and 480 is too expensive considering it's performance.

Well, if you plan to get a 5870 and add another one for Crossfire, then it would not be a good option as Crossfire does not scale as well as SLI.
July 20, 2010 9:49:50 AM

I don't know what I plan yet. 460 sli is very tempting for it's high performance but it's loud, hot and multi-gpu implementation will never be as good as single card's. If i decide to go for a single card I think it would be 5870 (or 480 if it gets cheaper).

Well you saw the review - it is not that loud or hot.It is even cooler than a single 5870.
July 20, 2010 10:09:28 AM

And that's why I'm probably gonna go for sli. Thank you all for your help and thanks Tamz_msc for the review.

For the most part what core temperature measures it the efficiency of the cooling system at removing heat from the GPU core. Saying the card is "cooler" based on such is misleading. How much heat the cards are giving off is directly related to their power consumption(basic thermodynamics.)
SLIed GTX 460s are the best deal for the money right now in terms of performance, exceptionally so when overclocking is taken into account, but they do have some drawbacks.
If you aren't going to go for SLIed GTX 460s I would recommend OCing an HD5850 or GTX 470. Like the GTX 460 they can both OC a ton and will give you much better value for the money than an HD5870 or GTX 480.

Hm thank you for your advice. If I decide to go for a single card I will take it into account. Maybe you have some comparisons of OCed 470 or 5850 compared to stock 5870?
July 20, 2010 10:50:25 AM

Go for the 5870 IMO, yes the SLI config is about 30-40% more powerful however with the 5870 you can add another one in later and they scale reasonably well and both can basically play any game bar Crysis/Metro at max settings with 8 x AA at insane frame rates. SLI GTX460 will also use 300W+ and the 5870 will only use about 180W, also the 5870 will be cooler and quieter and you will have no issues with scaling. However most games do scale with well with SLI and CF now.

Both the GTX 470 and HD5850 can generally OC 30-40% with an increase in core voltage. At those speeds both cards will be considerably faster than a stock HD5870. The HD5870 can OC as well of course but not to such a spectacular degree(about 15-20%.) I've seen comparisons of the HD5870 vs HD5850 when both are fully overclocked and at that point the HD5870 is about 6-7% faster which is why I say it isn't worth the extra $100 or so. I haven't seen a direct comparison of a fully OCed HD5870 with an OCed GTX 470 but I suspect the 470 would actually be slightly faster. Keep in mind the 470 is a GF100 processor and they do use a lot of power/give off a lot of heat. Then again if you have good case airflow then heat issues may not be that much of a concern.
Keep in mind that SLIed GTX 460s are on another level entirely. At stock they are nicely faster than the GTX 480 and close to an HD5970 and they can also normally OC about 30-35%. Apparently they are quite quiet on the reference cooler as well;

Well the price and performance are the main factors that make SLIed GTX460 the best (i think) choice for me. Noise level and heat were always important for me but you can't have everything I guess. CF 5870 is not an option for me because I don't want to spend that much money for a new graphic card.
July 20, 2010 12:38:21 PM

Go for MSI Cyclone GTX 460 or Asus. They are very cool and quiet I guess.
July 20, 2010 12:42:45 PM

I am thinking actually about GF GTX460 1024MB 256bit Sonic. Oh, and which version should I choose - 768MB 192bit or 1024MB 256bit ? Is there a big difference in performance?

For SLI I would stick with the 1gb cards. With a single card the memory/bandwidth difference isn't a big deal but in SLI the memory subsystem is redundant while the processing power gets added together.
July 20, 2010 1:02:38 PM

Well the thing is that I'm gonna buy those cards in my friend's shop (therefore cheaper) and the only 1Gb version he has are Palit and Gainward. The others are 786
