Hello, i'm new to these boards, found them while looking trying to research what I'm going to get for a new system. I'm hoping someone here could help me out a bit. I'm upgrading to a 939 motherboard which has already been ordered, this one to be exact: http://www.newegg.com/Product/Product.asp?Item=N82E16813131524 I'm looking into these two cpus: http://www.newegg.com/product/product.asp?item=N82E16819103531 http://www.newegg.com/product/product.asp?item=N82E16819103539 I'm nervous about getting one that wont be compatible with the motherboard. I'm still new at building (done once before). Is there anything specific about those that could cause problems with my new mobo? Anyone have a reccommendation of one over the other? will i see a difference in the 3800? I have a little over $400 for a budget, and already have the mobo, and a pny 7800gt video card. I can use my ram from my current computer and harddrives and soundcard. I really need a new powersupply too, but its overwhelming looking at so many. Any help there? I'm not even sure which brands are good and which arent. If i have anything left over i'd like a new case and some sata harddrives, but those will probably have to wait. Thanks for looking. Hopefully i can help somebody else out sometime.
