Which one is better (future-proof taken into consideration) and also which brand should I get it from (Asus, MSI....etc)? Thnx. I will be overclocking the cards to as high as they can go.
Well from what i read on forums that the GTX 580 is dropping in price to $399.99 in a couple weeks or so, that being said the GTX 560 or GTX 570 might drop in price also. Hopefully the GTX 570 will drop to $250 lol..crossfingers!...Anyways just wait a couple weeks see if price drops.
A tough decision... I recently also had to make. In some ways the head says SLI 560 is a smart decision while the heart desires the power of the 580! I went the gtx 580. From a future proofing perspective a second gtx 580 18months+ down the track puts you back in the game with a formidable setup... with 2x560's you're (sort of) locked in. If you can wait, I'd definitely see what happens to the prices over the next month, with the gtx590 on the horizon... Brand-wise my research pointed to EVGA, Asus, Gigabyte. Go for best warranty.
for a 580, would 1.5Gb be sufficient to max out all games on 1080p? because i was considering either the MSi lightning 1.5GB or the Phantom 3GB or Asus DirectCU II 1.5GB (I am in Britain so dont think i will get any price drops)
Yes that is true but that's theoretical.
Lets say you have a 1080p 120mhz LCD.
both are going to spit out frames just under the refresh rate. You can only get 60 or 120fps max at any resolution. So that 10 percent becomes even.
Now lets look when you up the resolution or quality. 1 setup is going to hit a wall with 1gb ram the other is not with its 1.5gb ram.
Then we still have to look at the sli issues you get sometimes. 1 580 max out everything you got space for another down the line when it can't perform anymore.
So you can't say one setup outperform the other we are in the day of the LCD we have to play with vsync on. So you won't get higher than 120fps.
i was having the same conflict but dadiggle have a very good point for the gtx 580 that i wasn't see but now i will get the gtx 580 or even the gtx 570 will be good
you really think 1gb of vram will be great in a few years? i think NO. no offence mate.
Yes I do, so long as we keep getting held back by consoles. Fact is 1gb is either going to be more than enough by a fair bit, or significantly too little - by this I mean, for example, look at Metro 2033. I can enable all settings maxed out (Very High, 16xAF, DX11, tesselation...) with my 1gb 5850s, however, the limit comes when I have all that and then enable both 4xMSAA and Depth of Field. Both are mem hogs and the requirement for both goes up to around 1.5gb, but with one or the other only, it runs just fine.
Games just aren't getting that much more demanding, and even if they do, it's a simple matter of turning down 1 setting. Now, perhaps that's not acceptable for some people but let's be honest, it's not a big deal.
If you look at the 6950 1gb vs 2gb, even at 2560x1600 the performance is the same.
