Hi all, im building a top of the range gaming rig to hopefully last me a good few years and have around £600 to spend on nvidia based graphics as I already have the nvidia 3d kit
my question is would i get better results for FPS and MMO games from....
3way sli GTX 560Ti 2048MB 822mhz
as seen here:
1 x GeForce GTX 580 3072MB 772mhz
as seen here:
or would you recommend a different card or set of cards for my budget
2 560 ti cards in SLI will outperform a 580 3GB. 3 of them will be substantially faster (though the scaling of the third card is not as efficient as using only two). Keep in mind that 3 560 ti's will also use substantially more power and will require 3 6-pin PCIe connectors unless you want to use converter cables. a 3 way SLI setup is overkill for any mmo that i'm aware of. Any dips in FPS that you would experience would not be gpu driven.
Also keep in mind that for many users the additional VRAM is not going to provide any performance benefit. What resolution are you using?
I'm pretty sure those 560's can only be run in 2-way SLi.
i thought that at first so contacted the company reply was...
"depending on the board you can use these for 3 way SLI."
im presuming they mean the mother board and not the gpu board... but will make a telephone call to them before buying
I have a couple of 560ti's in SLI running behind an overclocked 2600K, and at 1920x1080 I see absolutely no reason yet to need a 3rd one. A second monitor will have a slight effect, but it'll only be a few fps. I would definitely just grab 2 560ti's and try them out first before I spent money on a third.
Seriously 3 way sli is overkill. In my view 2 way is the way to go. With 3 way the gain in performance is low compared with the financial outlay as well as the demands on the rest of your system (power, cooling etc). For me, the choice is between the following two options. I'm assuming you're buying now.
- a single GTX 580. Pros: no sli issues (although these are minimal these days). Allows you to add a second 580 when you need a boost. Cons: less performance than option 2 below.
- two GTX 560 tis or 6950s. Pros, much better performance than a single GTX 580. Cons. Lacks the upgrade path of option 1. If you need more power than this option can provide (and you are in a very small minority if you do) then you can go for two 570s or 6970s.
A final option is to wait as nvidia and amd's next generation is round the corner
