Thanks a lot for the info ShyGuy! - I am convinced that I should settle for a decent mobo in order to buy a great video card. I'm basically 99% sure that I'm going to go with the UD3R - I will do that so I can use the money I saved to buy a really great video card, like you said.
Zepper - I will read that when I start building, but right now my only concern is to gather all the parts. Yeah, I read somewhere else too that the power supply and case are extremely critical. I will definitely PM you when I start researching power supplies - but I can only handle researching one part at a time - I think the next thing I will research is the video card.
Thanks for the help so far guys.
