Sli/Tri-Sli Performance  

post #1 of 9
Thread Starter 
Hi, I'm in the middle of deciding on parts for my i7 build, and am currently attempting to decide on a motherboard. Would I notice any difference in performance having true 16x lanes for sli/tri-sli, over having 16x, 8x, 8x. Also is tri-sli even worth it? I've looked at some benchmarks, and it seems in some games it scales really well, and in others it has little to no performance gain. Is this something that can be fixed through a driver update?

Thanks for the help!

if you're not on a budget either the ARIIE or Evga classified is good for tri-sli setup. If crossfire go with bloodrage if you don't mind 3 memory slot.

depending what cards you plan to tri-sli, and what you already have, you'll need to invest in:
- 3 of the same cards
- A power Supply that can support 3x sli
- Some form of direct cooling for your three cards
- A capable motherboard
- A case that's big enough

consider the price for all of the above, and then you'll be able to make your own decision on whether or not tri-sli is worth it. After all, benchmarks are just ... benchmarks. You don't need 75+ fps in crysis to enjoy it

i dont think any game even requires a tri-sli, unless you plan on doing it with older cards, like the 8800

Alright thanks for all the help. I think I'll stick with sli/crossfire. Do you guys recommend any crossfire/sli x58 boards? I'm not technically on a budget but I really don't want to spend to much for stuff I would use/need, when I can use that money on other components. But I'd be willing to spend the money if it is worth it in the long run.

I do like the Blood Rage but I sorta want to have 6 memory slots, thanks for the suggestion though. Lately I've been looking at the Asus P6T Deluxe V2. But I've heard Asus' customer service is sorta bad, and EVGA's lifetime warranty is definitely appealing.

Thanks again!

The MSI X58 Eclipse will let you do XFire or SLI.
But its a little expensive.

If the Bloodrage doesn't appeal to you and you're leery of Asus's customer support, that doesn't leave many options (unless you start looking at low/mid-level boards). The eVGA Classified will certainly do the job, but at a price premium. I would have to recommend the DFI LanParty UT X58-T3eH8. Granted, DFI's customer support is non-existent, but it's always been like that, even in the Socket 939 days. Technical issues were handled through DFI's forums by charitable senior members. All that aside, it's a very underrated motherboard and you should have a blast with it. I would advise you to buy warranty through the retailer where you buy it from if you're going with this board.
