Need help choosing motherboard for system

whats your budget for the board,and what will you be using the computer for?,and are you planing on overclocking?

Hmm. Haven't really got a budget, but I will be using the computer for high performance gaming. No overclocking.

Would "GIGABYTE GA-Z68X-UD4 Sandy Bridge" be a good choice?

the Maximus IV GENE-Z/GEN3 would be a better choice,here check it out

But what's up with the microATX size? Doesn't decreased size on motherboard mean worse performance?

A Micro ATX motherboard is generally the same as a full size, they just don't have as many expansion slots. As far as performance goes, the Micro is going to be the same as long as it has the same specs on each component. Meaning, if it has a x16 PCI-E Slot, a standard FSB speed, Dual Channel Memory, SATA etc..

I will be running two of these gfx cards in SLI in the future.

I got another guy saying that P67 would be better instead of Z68, is that true? Performance wise.

P67
The P67 chipset was available at the launch of the Sandy Bridge CPU. The upside of this chipset is it supports the option of running two dedicated graphics cards in SLI or Crossfire and the option to overclock K series CPU’s.

The downside is not being able to support the integrated graphics on the CPU so a dedicated graphics card is a must. It makes it a popular choice for the enthusiast and gamer.

Z68
Launched 5 months after the P67 and H67 chipset the Z68 chipset combines the advantages of the H67 and P67 Chipset so that overclocking, dual dedicated graphics cards and use of the integrated CPU graphics is available. Whilst on the surface it would seem that this would be the chipset to go for.

The only real advantage is for users that wish to access the HD graphics features such as quick sync, but considering it’s only supported by very few transcoding programs and there are not many people out there that need or will want to transcode, it makes it almost pointless to choose Z68 over a P67 chipset.

Same applies to users that want to overclock the CPU but use the onboard graphics card; it’s a very limited market.

Finally, another feature of a Z68 chipset is known as SSD caching which is where it allows the use of a small (say 10 or 20 GB) Solid state hard drive to act as a cache for a larger ‘traditional’ hard disk. If you are already planning the use of a Solid State drive this feature is redundant.

If you can’t afford a decent size SSD (40GB+) then there are more cost effective ways around using a small SSD and SSD cashing like spending less on a motherboard, (H67 chipset or even a P67 chipset) and putting the saved money into a decent size SSD.

so Z68 is ALOT better in both the short and long run

Thank you very much. +1
