i want to buy a pc and i need a best specification for hoardware , can any body tell me which hardware i buy for my pc.
thank,s

It all depends on your budget. For $1200-1500 USD you can put together a great machine.

What i do is find the parts which are the best deal - by reading reviews on sites like newegg.com. Why buy a Quadro FX 5600 card if a $200 8800GT will do just fine? You get the point.
