Mobo for SLI?


Jan 6, 2012
I'm currently upgrading my system in 2 stages.

stage 1
i5 2500k
8GB DDR 3 1600 G-skill
MSI GTX 560 TI twin frozr II

stage 2
2nd 560TI
another 8GB RAM

I'm just wondering if the

ASUS P8Z68-V LX LGA 1155

is a good board to grab for SLI.
i can spend up to 130 on the board
Just my opinion, but so long as a good single gpu card will do the job, I see lots of advantages on not planning on sli or CF.

Here is some of my reasoning:

1) How good do you really need to be?
A single GTX560 or 6870 can give you great performance at 1920 x 1200 in most games.

A single GTX560ti or 6950 will give you excellent performance at 1920 x 1200 in most games.
Even 2560 x 1600 will be good with lowered detail.
A single GTX580 is about as good as it gets.

Only if you are looking at triple monitor gaming, then sli/cf will be needed.

2) The costs for a single card are lower.
You require a less expensive motherboard; no need for sli/cf or multiple pci-e slots.
Even a ITX motherboard will do.

Your psu costs are less.
A GTX560ti needs a 450w psu, even a GTX580 only needs a 600w psu.
When you add another card to the mix, plan on adding 150-200w to your psu requirements.

Case cooling becomes more of an issue with dual cards.
That means a more expensive case with more and stronger fans.
You will also look at more noise.

3) Dual cards do not always render their half of the display in sync, causing microstuttering. It is an annoying effect.
The benefit of higher benchmark fps can be offset, particularly with lower tier cards.

4) dual card support is dependent on the driver. Not all games can benefit from dual cards.

5) cf/sli up front reduces your option to get another card for an upgrade. Not that I suggest you plan for that.
It will often be the case that replacing your current card with a newer gen card will offer a better upgrade path.
