Hi,
What I would do is go to Newegg and look at the reviews on the boards themselves. For example if I wanted to choose between a FoxConnn and BioStar board for an Intel Socket 775 I would go and see the following:
Foxconn G31MV-K LGA 775 Intel G31 Micro ATX Intel Motherboard - Retail
20 Reviews (70,15,10,5,0)
BIOSTAR P4M900-M7 FE LGA 775 VIA P4M900 Micro ATX Intel Motherboard - Retail
4 Reviews (25,50,0,25,0)
Foxconn G9657MA-8EKRS2H LGA 775 Intel G965 Express Micro ATX Intel Motherboard - Retail
75 Reviews (36,24,13,8,19)
BIOSTAR G31-M7G DVI LGA 775 Intel G31 Micro ATX Intel Motherboard - Retail
3 Reviews (33,67,0,0,0)
The numbers in the brackets are the break down of the percents of stars. For example if it said '10 Reviews (20,10,30,10,30) means that:
5 Stars: 20%
4 Stars: 10%
3 Stars: 30%
2 Stars: 10%
1 Star: 30%
Now the most important parts of this are the number of reviews and the breakdown. I read once that the majority of people on the internet rate items high. There are various psychological reasons for this I won't go into. Also, people have to be REALLY upset to rank something low. So now what I do is add up the bottom 2 Star Rankings and I seperate out the 3 stars ranking:
Foxconn G31MV-K LGA 775 Intel G31 Micro ATX Intel Motherboard - Retail
20 Reviews
3 Stars10
1 AND 2 Stars 5
BIOSTAR P4M900-M7 FE LGA 775 VIA P4M900 Micro ATX Intel Motherboard - Retail
4 Reviews
3 Stars 0
1 AND 2 Stars 25
Foxconn G9657MA-8EKRS2H LGA 775 Intel G965 Express Micro ATX Intel Motherboard - Retail
75 Reviews
3 Stars 13
1 AND 2 Stars 27
BIOSTAR G31-M7G DVI LGA 775 Intel G31 Micro ATX Intel Motherboard - Retail
3 Reviews
3 Stars 0
1 AND 2 Stars 0
Now amount of Reviews play a role. The more reviews the more likely they are reliable. I usually remove the boards with less than 40 reviews but for this example I'll take it down to two:
Foxconn G31MV-K LGA 775 Intel G31 Micro ATX Intel Motherboard - Retail
20 Reviews
3 Stars10
1 AND 2 Stars 5
Foxconn G9657MA-8EKRS2H LGA 775 Intel G965 Express Micro ATX Intel Motherboard - Retail
75 Reviews
3 Stars 13
1 AND 2 Stars 27
Using the reviews and the 1 thru 3 Stars I would say that the G9657MA model will likely give me a 27% chance of being unhappy with it and a 13% of being satisified. The G31MV-K gives me a 5% chance of being unhappy and a 10%chance of being satisifed.
Even though the 20 reviews of the G31MV-K isn't enough for me to be confident of the numbers I would likely NOT get the G9657MA because I have a 27% (almost 1 in 4) of being unhappy with the board. I would look for a better board.
Please note this is how I would quickly choose a board. If I had specifications I was working off of (like Max SATA connector, onboard video, etc, I would adjust accordingly). I would also after narrowing down the boards read the reviews to see what the most complained about problems actually are.
I hope this helps. If you have any questions I can try to answer them or explain what I mean better.
Cheers,
Adrian
