need some help

[dagz]

Hi, im about to order some new computer parts and i have some questions. I want to order

http://www.zipzoomfly.com/jsp/...uctCode=80717-R-241143

My question is, is ddr 3200 the fastest i can go for memory? (atm i have rd and dont know much about ddr)

Does all 4 memory banks have to be filled on the nforce 3 boards? If so i will have to go 512/512/256/256 is that ok?

Does a radeon 9800pro work on the nforce 3 boards?

Thanks!
