hello, building my first p.c. and wanted to go with the ati radeon 9600 pro. i was looking at the 256 mb version but will there be a major difference between it and the 128 mb version. also what brand whould i look at? (saphire, power color, etc) kinda confused, because some of the sights show it one way and another site will show it another. if anyone has the time to maybe find the cheapest 9600 pro on a site that would be great if you just know of one. thaks for any replies.
