Is GTX 580 SLI enough for 2650x1600 - Page 3

post #21 of 42
2gb 560's are also an option, they should beat out 1x580. Like others have said though I would go for the 3gb 580s if you can afford it.

Either way with the amount of money you have already invested in your set up I would not settle for any less than 2GB of VRAM at your res, and even 2GB is just 'enough' rather than the 'more than enough' you would get out of 3GB 580s.
^He's not exaggerating btw. I've spiked up over 1.5 GB of VRAM usage at just 1440p. If you don't want to make any sacrifices to AA/AF/Tessellation, you'll definitely want a card with at least 2GB VRAM.

A standard 580 has plenty of processing power, but it won't matter if you reach a VRAM choke point. SLI 3GB 580s should be able to handle any title out there at 1600p.

yes that set up will max crysis. 'nough said

44 fps. a little overclock and you'll be in the 50s.

and don't listen to those people who say 1.5 GB is not enough. 1.5 GB is plenty for 1600p. you only need 3 GB if you are using 3 1600p panels, and by that time, you'd want tri or even quad SLI anyway. by the time that you turn on AA high enough that 1.5 GB is not enough anymore, then your fps would already below comfortable levels.

so two normal 1.5 GB GTX 580 in SLI is plenty for most games out there.

Like I said before 1080p is about 2 million pixels, 1600 is about 4 million pixels. Therefore a frame buffer of 1.5GB at 1600 would be similar to running a 768MB frame buffer at 1080 or in other words not ideal at all. Also I have seen about 1187Mb of my 1.25GB used up in Starcraft 2... at 1080p.

Yeah, don't listen to people who actually play above 1080p... that's some really good advice.

If you notice, the chart you linked is Crysis on GAMER with only 2xAA. That is not "maxing" anything. Try Crysis on Enthusiast with 4xAA at 1600p with only 1.5G VRAM. I guarantee you'll find a choke point.

I'm using one 1440p panel. This was my VRAM usage from a few hours of playing DA2 with 4xAA.

OP, I'm in agreement with james here - especially that last part. It really boils down to what games you want to play and how you want to play them. Of course, if you are looking to max out all the heavy hitting games (Crysis, Metro 2033, Dragon Age 2, etc.) then the 3GB cards would be a given, but even on a single 1600p display, you're unlikely going to see the full usage of that VRAM. However, if you're willing to compromise, you can make the 1.5GB card you already have work for you. And frankly, after spending $500 more or less on your card, wouldn't you want to see some value from it?

I play in excess of 6 million pixels (just shy of 7 million), and I can tell you that the 1.5GB 580's do a wonderful job at this resolution with anywhere from no AA to 4X AA depending on the game. At high resolutions and dense dot pitches like your's (ie. 1440p and 1600p), AA needs are highly subjective. Some may not notice or really need a high level of AA to have an enjoyable experience, while (obviously) some do.

While I think VRAM is certainly an issue that does need to be addressed, these days it seems members here automatically associate anything higher than 1080p with 2-3GB of VRAM and Crysis. Whatever happened to the enthusiast side of things? It's not all about throwing money at a problem to solve it! Play around with some settings, tweak your games a bit, and just have fun with what you have considering the fact that your card *still* represents the top echelon of enthusiast hardware.

The main point I want to make is this: wait until your monitor arrives and play the games that *you* actually do play, and then decide where your standards for performance lie. Honesty, I think it's irresponsible of a lot of people to just dismiss your situation and just say "sell your card and get a better one." It's as if it were so easy to do (especially in Hawaii) and so easy to accept a substantial loss for a card that is barely 6 months old. Remember, it's not their money you are spending - it's your own.

I'm not going to continue to sing the praises of more VRAM because I think you should have enough info to make your decision now, but I figured I would leave this here, it's confirmation of an EVGA 3GB 580 that should be available in the coming weeks. Have fun with your rig whatever you decide!

This is true to an extent, and certainly the OP can decide for himself. But I will say from experience, the U2711 actually has the smallest dot pitch out of any of the "big" screens (smaller than the U3011) and I can still see some jaggies up until 4xAA in most titles. That's still a massive improvement over my old 1080p monitor though, where I preferred 8x or higher to keep things smooth.

That said, games do look gorgeous without any AA on a high res IPS screen, but the OP's first post specifically asked, "will 580 SLI be enough to max any game out in max quality with AA on 2650x1600 resolution?"

That sounds like someone who doesn't want to make any IQ sacrifices if possible.

It's up to you OP, and of course, testing it for yourself once you get the monitor is always sound advice. If you have the option though, and it seems EVGA will be making it much easier very soon, I would definitely recommend grabbing a 3GB card. 580s have so much horse power, why limit yourself when you very realistically could max every game out with a bit more VRAM?
post #30 of 42
i remember 10 months ago when you didnt have to spend $1200 dollars in GPUs to consider yourself at the minimum hardware level for 1600p

short answer yes,
long answer, buying the card with the most vram possible starts giving you some nice fps increases as you go over 1080p/1200p.
