Apparently on the iBuyPower computer configuration I can either select the AMD Phenom™ II X2 550 Dual-Core (my current selection) or the AMD Athlon™ II X4 620 Quad-Core and both are at the same price. (so if I switch to the Athlon Quad-Core, the price won't go up on me.) Which should I choose? Stay with the Phenom dual-core or switch to the Athlon quad-core? If I should change to the Athlon, why? What are the differences, advantages, pros/cons, etc...
Keep in mind that I'm no "hardcore" gamer, I don't edit videos, audio, etc...etc... so should I just stay with the Phenom or what?
