I am looking at getting a new AMD computer & I was looking at the Aopen XC Cubes. I saw that there was a 754 and a 939. On newegg the 754 is 150 ( http://www.newegg.com/Product/Product.asp?Item=N82E16856140021 ) and the 939 is 300 ( http://www.newegg.com/Product/Product.asp?Item=N82E16856140018 ). They also had a refurbish 939 for 220 ( http://www.newegg.com/Product/Product.asp?Item=N82E16856140018R ) . I was only on planing to get the Athlon 64 3000+ Venice in either 754 or 939. I also want to use a 6800 GS video card. I want to know if the 754 is the way to go b/c it is cheaper or go with the 939 b/c it will be more expandable. I really like the design of the XC Cubes but if some had a really bad experiences or if this computer is not good for mild gaming then please tell me.
