Thanks For the info. I was not sure. I saw from tiger.com and newegg.com where some motherboards have 2 or more pci 16x slots. I am not too big in gaming part. I like watching movies and other videos too. I am still using windows xp 32 bit. I want to use little bit more then 8 gb of memory but i know that is for 64 bit not sure if it will work with 32 bit but hell 16 gb ddr 3 will work with 32 bit and 64bit OS. I did go to school to learn about my computers and networking and att feild techs sure love how i know about telecomm and cable comm.
