A friend of mine is building a good pc for gaming, my current PC is 3 years old with Asus III Crosshair, ATI Radeon 5xxx HD, and AMD Phenom II x4 and i can still run almost everything at max settings so i suppose nowdays you can get a better PC for $700-$850 budget? i am not much into hardware so i need somehelp on getting the best parts that worth their money.
