Her har et af verdens førende test/review site 2 af de nævnte kort med, jeg citere fra deres test:
Conclusion - ASRock Z77 Extreme4
I had high expectations of the ASRock product due to what we have seen in previous chipsets. Over time, they have developed this knack of offering a good performance product at a great price, and a large amount of free kit in the box to sweeten the deal.
The Z77 Extreme4 is the lower end enthusiast board coming out from ASRock...[i]Features such as mSATA (Gigabyte), included WiFi (ASUS), Intel NIC (ASUS, MSI), price ($135, ASRock), auto-overclocking (ASUS, Gigabyte), and performance are all up for grabs. None of the boards today stands out as the ultimate choice for everyone - if you want control, go for ASUS; if you want mSATA, go for Gigabyte; if you want a full Z77 on a budget, go for ASRock; and if you want a very easy to use board, go with MSI. It all seems to be a price/feature set battle that a system builder will have to consider.[/]
