A new powerfull motherboard for my p.c.,,,

Cool! I am a computer enthusiast as well. Well the other guy has a point. More likely, most current motherboards that support core i7 has ddr 3, also ddr 3 is much cheaper than getting old ddr 2, because memory modules such as ram tend to become more expensive as they get older, become phased out and obviously no more supply, thus becoming ridiculously expensive that newer and faster modules. Anyway, you should get at least 2gb but I highly recommend getting 4gb to 8gb, if you can afford it and settle for an nvidia or ati card that has a fast video ram, because it's not always about how big is the video ram, example an nvidia card with 512 mb (ddr3 video ram) will perform better than cards with 1gb video ram (ddr 2). :(, I want to build a fast computer also but I don't have the money, well one reason also is I don't play games anymore, that's why I don't really need a very fast computer at the moment.
