if cheap and PCI express are your only criteria...
look for boards made by BIOSTAR, PCCHIPS, ASRock, or ECS, but be warned, these boards have the highest return rates. My son works in a Computer store and he says probably 80% of the RMAs he processes are for boards made by these companies.
But I would go with a better quality board made by ASUS, MSI, ABIT, Gigabyte or Soltek
Sounds like you experience level isn't real high so I wouldn't suggest a high end board for you. Instead, try to stay with boards costing between $80 to $100. These are usually well made boards with the features most people want\need.
You see he is right - it looked that way to me too... I mean, like I said I have the same mobo and a subsequeent Neo2, but I know that PCI-Express came out after the Asus was discontinued and was only just moving into production as the Neo2 was being made. If you know what a PCI is, what a Bus is, what an AGP is and how they interact then you are getting the smarts here - google and read and do not be so sensitive. The guy was giving you some very good advice bang on topic, IMHO.
I'll try getting back to topic - now that you know you do not have a PCI express enabled mobo, what made you look for one? Contemplatig a new system build and starting your spec from the graphoics card backwards? (Just a wild guess that last)....
I was not trying to insult your intelligence and I apologize if you took it that way. I was commenting on your experience level, which from your posts would indicate you have not had a lot of experience with computers. You should not be offened at that. We are all noobs at some point and we are all capable of learning.
Keep posting here and asking questions and you will learn and gain knowledge, and one day be able to help others. And sometimes when you help someone you'll be saying to yourself "Wow, I remember when I didn't know anything about that and someone on the forums was patient with me and helped a lot".
The advice I gave you, however, is still valid. I was only trying to help.
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
