Have around $500 or so for the components to build a general pc. Thinking of using Windows 7. Realize this is an extra $100 or so. With the budget of $500 it seems AMD is the way to go. Need some recoomendations on Mboard, processor, memory, Hard drive-seems Western digital black?, DvD/RW, video card, sound card if possible and really needed etc... Would buy parts from various online vendors. Any help much appreciated. Can go higher in the budget if it really will be that much of a benefit.
