Desktop PC Question???

First OFF..64-bit is for scientists and engineers..and any PC-HDWR that states its compatible w/64-bit...requires a 64-bit OS and all of the DRIVERS...Secondly...it is my belief that getting all that together requires a IT-Professional..I priced a 64-bit Operating System and it cost $$1200.00///and was made up of 6-DISKS for Installaion..//..from what I have read on this Yahoo webpage(ANSWERS)I doubt any person here can RUN a 64-bit OS...Here's my research--ON A 64-bit PC..//..its merely a Parts List(starting point)..Titled "Vista 64 Bit"...CPU-Q9450...Mobo-DX48BT2...PSU/50… Vista Home Premium(64-bit)...RAM=2GBs(2 x 1Gb)1333MHz...S-ata HDD and Optical Drives...New Keyboard+Mouse(USB)...//Dual Processor Support//...Buisness,Ultimate,Enterprise… OSs.[end]
