Hi i have a P5LP-LE leonite motherboard on my HP m7760n(RK570AA) computer that i got about 3-4 years ago and the motherboard has a socket LGA755 CPU slot. I got a Intel Core 2 Duo E6400(2.13GHz) CPU and i want to upgrade it. Whats the best CPU that can play high settings very well with a XFX ATi Radeon HD5570 1GB graphic card that I'm gonna get soon. I want to play games on high settings like Borderlands, The Sims 3, Sims 3 pets, Left 4 dead 2, GTA IV, Crysis 2, Just Cause 2, Fifa 12. So what the best CPU for LGA775 with the XFX ATI Radeon HD 5570 1GB Graphic card that can play those games on high settings that i listed above, my budget is $150 for the CPU
