SLI 580 or Tri-SLI 570 or 680?

post #1 of 45
Thread Starter 

I've been scouring the interwebs trying to see if there's a website that has done benchmarking on this, but sadly I'm at a loss.




I'm soon to be in the market to replace my 2 AMD 6850s and going green with either 2 Superclocked EVGA GTX 580s or 3 Superclocked GTX 570s. The price difference between the two really isn't that much of an issue at this point, but I'm trying to figure out what would be the best possible solution.




I have an ASUS 990FX Sabertooth motherboard (with plans to upgrade to Crosshair Formula V) that runs in either X16/X16 in SLI or X16/X8/X8 in Tri-SLI.




I don't really know how big of a hit it'd be with the 2nd and 3rd GPUs running at half(?), so I'm wondering if anyone else knew.

3 GPUs vs 2 GPUs. What are you paying for each? Normally 3 GPUs will always be better (when the cards aren't gaps apart like these two), but if you can get the 580s for a nice price, I'd go with those.

Although I wonder if 3-way SLI will be bottlenecked by your CPU? Hopefully someone familiar with AMD CPUs will be able to comment on that as well.

with that phenom x4 you will run into one hell of a bottleneck running tri SLI. Also remember scaling...2 is better then 3

Well I'm in the process of upgrading my CPU to the new FX-8150, new motherboard, new PSU and new GPUs so hopefully bottlenecking won't be an issue.

And I just looked it up on Newegg and it's the difference of about 10 dollars between 3 570s or 2 580s.

2 x 580 and add no 3 later. Or why not a 7970. I went from GTX 570 Sli to ONE 7970 and am blown away - its chalk and cheese.

Personally, if you're going to spend that kind of money on GPUs then do yourself a favor so those cards won't be bottlenecked and go with a 2500K or 2600K.

 

But personally, I'd go with 2 cards. 2-way SLI 580s destroy the games. Although it depends on how much vram you're needing.

 

- Resolution?

- Multiple Monitors?

- E-peen? :P

I'm planning on jumping the fence because I've had issues with AMD cards as of late. No games seem to like xfire very much and I have a gloating cousin who's got 2 570s and he brags about how good things run with his 2 570s. Also, I'm still playing the crap out of Skyrim and even with new drivers and everything, I'm still stuck with choppy framerates, downloading new xfire profiles, changing values and various settings throughout Windows, just so I can get the game playable.

I've looked into going over to Intel, but I just don't really know. I mean, I'm planning on doing an overhaul regardless, but even now with the Ivy Bridge soon to come out, a 2600k is still 320 dollars, plus the cost of a new motherboard that still has the same specs that I'm looking for with the Crosshair V; dual X16 slots or X16/X8/X8, 2133 MHz RAM capability with all 4 lanes next to each other (I just recently purchased a RAM cooler) and aesthetics-wise fit the color scheme (black and red).

Well... yeah, kinda. I've seen some really sick watercooled Tri-SLI setups (this case mod by Saer is my favorite: Skynet Case Mod) and I want to follow suit in a way.

But honestly, I just want the most I can get for my money at this point. Which is why I came to you guys asking for your opinions biggrin.gif

Well, by what you've given me since my last post, I say go with 2 580s. AMD's just not that strong right now in the CPU department, and while the 2600k is $320, it's worth it. Maybe go with a single 680 instead? I'm guessing your resolution is 1920x1080?

any chance near a microcenter get a cheap 2500k that way, or hit up the for sale threads here and upgrade for a decent price and then throw more $$ at a 680
