It isnt the best out their, it's a mid line
You do understand, that you can get that CPU to AT LEAST 3500+ speeds without trying at all.
You can also choose to get a 200$ bundle with a 3000+ and a cheap motherboard, but be aware that the 2400+ mobile will run faster, a good SKT 939 motherboard costs 150$ so your likely going to get a crappy motherboard
After hanging around these forums for a while and doing some reasearch, you will learn that a mobile is a good investment.
This is basicly how they select a mobile. They make all the barton core chips. They go to a testing machinne, if the CPU can run a 1.45volts or whatever which most cant and if it runs very cool, it will be laballed as a mobile.
Because it can run at lower voltages, you just bump up the speed, and voltage and you will have no heat or stability issues.
Nubius, a moderator on this board, gets his 2400+ mobile OC'ed with a 6600GT (EVGA, slower than my XFX) to be very close to my 180$ asus a8v and my 3400+ OC'ed to 3800+ speeds.
He's within 8% of my score and his system costs alot less than mine. He goes and beats out a 3.8ghz intel in alot of his benchmarks. He even has 100mhz less on his graphics card.
And to play current games, a 200$ graphics card is nessacary. You had a budget of 600$ for a PC, and I gave you great suggestions.
EDIT: 200$ for a combo, a 3000+ SKT 939 their is 160$
