So i'm torn between a P55 setup with i5-750 (about $500) or a Phenom II X2 555 with a AM3 board with SB790FX, which may allow me to unlock the extra cores. The AMD setup would save me about $150.
I'd just upgrade CPU, mobo and RAM
If i go AMD, and am unable to unlock the extra cores, should I still see a night and day performance boost over my current rig? My thought was maybe to go that route now, and the i can always upgrade just the CPU later if needed
or should i just say to heck with it and go the Intel route? looks like that i5 can OC to 4Ghz pretty easily
