Which SLI for my budget & surround.

post #1 of 22
Thread Starter 
With the 560s out, I am sort of stumped as to what cards I should go for in order to sli and get Nvidia Surround going.

The computer in question is the one in my sig.

I have the following options:

1.)SLI GTX 560 (I'd probably go for the MSI Twin Frozr II since they seem to be able to hit 1GHz easily.)

2.)SLI Palit GTX 560 2GB (Not sure if the 2GB vram on each card would make that big of a difference.)

3.) SLI GTX 570 (Not sure what brand, but of course about $150-$200 more, but gives the option to go tri-sli in the future.)

Now giving all these options, I'd be running the 3 monitors in my system below for a resolution of 5760*1080.

Would I choose the standard 1GB 560s which I can get for about $500 from Newegg and simply overclock them and be fine?

Palit 560s for about $560 for the 2GB, I've never owned or even thought about Palit before so I have no clue how reputable they are or how well they would OC.

Or GTX 570s, with 1280MB and I higher cost of $700 or so for 2.

Also, I would think, but not 100% sure, that my PSU can handle all of these options, let me know if it can't handle the 570s, because they can just be eliminated as an option if that is the case.

In comparing these options, either compare the options all at stock specs or as if they were all overclocked. Don't tell me I can get the 560s and overclock them past 570s, because I would overclock the 570s if I had those.

I'm just not sure if 1GB of vram is enough, if the 2gb is worth the extra price, or if the price from 560 -> 570 justifies the end result.

I also wouldn't be buying these within a day or anything. This is future prep for say early to mid March, so if EVGA is releasing a 2gb 560 or if the 590s are coming and going to drop prices then I would like that info, although I think I've caught up on what's going on.

Thanks for the help guys!

For the high resolution the 2GB of memory would be nice to have, but leaves you with no option to go tri-sli, and the cards aren't as powerful as a 570. I would go with the 570 as it leaves you with an upgrade path, has more video memory than a standard 560.

Thanks for the input.

Any other input?

I should also add right now I pretty much play League of Legends, BFBC2, and maybe some Civ V or L4D2.

I am looking forward to Guild Wars 2 and TERA which I know both will take advantage of surround.

I don't think I've ever had a fast enough GPU to be able to play games with full AA/AF so I'm sure it wouldn't be a big problem for me if any of these options would limit those as I wouldn't notice the difference.

570, sorely because you have the option to go tri SLI.

Vram is not that important if you don't crank up the AA/AF that high which you sometimes find that you have to dial down because of the extreme high res. in some games.
Running surround is an entirely different story.
You soon find out you need more processing power.

NO surround needs more ram. Sure more processing power is needed (always) But soon you will find that ur card does have the precessing power and will be out of ram. So more ram is needed for surround. So id say go for the 2g 560.
Ill find you a review here on OCN comparing 2x 460 1g to 2x 460 2g.

EDIT: ah yes there it is: http://www.overclock.net/nvidia/8016...ream-card.html
Remember that 560 is better than 460. Not to mention when oc-ed.

If I'm not completely mistaken Xfire 6950 is just as good (if not better) than SLI GTX 570 at that high resolutions. That is with AA/AF of course.

Why am I suggesting this? Well, you can unlock the 6950's, it be shader unlock or flashing it to a 6970. Best price/performance card imo.

If you're going for high res, ATI is the way to go tbh.

2 x 570GTX souns good. Just consider that if you take this way, and want to go tri-sli, you'll need another PSU! So... The price of 3 570GTX + good PSU = $1250ish, vs 2 x 580GTX = $1000, im just saying!!
Any of the 3 choices you descrived would be awesome anyway!!
Good luck!

Although you'll gain performance, the use of a third card in Surround isn't needed unless you're gaming on something higher than 27" monitors. Sticking with 2 570's would be fine considering the games you are playing.

BTW; someone else had this same question and I believe they ended up buying the 560 2gb's. I can't find many tests comparing the 560 2gb - 570 in Surround, but from what I've seen they were roughly even.

Surround does indeed need a lot of RAM. I don't think even 1.2 GB is going to cut it. Civ V on my single 1080p monitor at 2xMSAA in 3D maxes out at 1008MB (out of 1024). I vote for the 2GB 560s in SLI.
post #10 of 22
2 560's a beefy start..also someone mentioned a 6950..but this gives a pain whether it can be unlocked safely..though personally i like the 570 for a mediocre performance(significantly it can play most games at decent FPS with High settings plus an option to 3-way SLI)..well it just boils down to your budget..

a non standard 560(2gb ones)will significantly perform better where there are multiple monitors plus a uber high gaming reso..
