I've been reading comparisons between the Phenom, Athlon and Fx.Me and I opted for the Phenom as it's slightly superior to the Athlon. The Fx is more modern and probably better but if I'm going to use programs that only use one core (mononuclear) I've read that the Phenom is better than the Fx. The processor no longer gives me a headache:

AMD HDZ965FBGMBOX - AMD AM3 Phenom II X4 965 Box CPU Processor, black - Amazon.es: AMD

I might buy a proper cooler for it later and do some OC.

Now the motherboard is what I want to resolver.Me I'm interested in having a motherboard with a USB 3.0 header to put it on the front of the Nox-NX3 case. Candidate and I look forward to your opinions:

Asrock 970 Extreme4 AM3+ 90-MXGIP0-A0UAYZ Motherboard

I can't find another one at this price that has an onboard USB 3.0 connector.

I don't care so much about the RAM, as long as it's 8gb DDR3 at 1333 or 1600, I don't think there will be much complication.

Muchas gracias, creo que de momento me quedare asi como estoy y ahorrare algo para pasarme de plataforma.
