I am planning to build a pc that will be able to run music software smoothly, like Propellerheads Reason and Cubase at the same time. Also as a casual gamer a pc that can handle new games effectively, however i am not over enthusiastic about the best graphics and fraps but i would like a motherboard that i can upgrade during the next 2 years or so.
My budget is tight at around $500 - $600 for the initial build.
I am thinking about building an AMD system. I already have a monitor, speakers, keyboard, mouse and 500Gb WD SATA Drive.
If you are in the UK and buying/building it in the UK I think it would be better to have your budget in pounds. Also are you bound to buying from Amazon? I ask because there are other sites which might be able to get better components from.
Your motherboard is a DDR3 one, so DDR2 isn't compatible and won't work with that motherboard.
64-bit OS can use more than 3GB of RAM, and this includes the video RAM, so the installed components from your current suggestion would be about 5GB total, and the system wouldn't be able to recognize 2GB of it. I'm sure that the software/uses for this system would be much better of with a 64bit OS capable of seeing and using all the RAM available.
+1 to everything jsc said.
