I've got an oppertunity to get my hands on an FX53 for $100. I've already got a 3500+ that oc to 2.5 with the stock fan. Is it worth it to get the FX and oc it for the price? Isn't an FX53 pretty much a 4000+?
The FX-53 is a Clawhammer core, so it probably won't OC as well as a San Diego/Venice core, nor will it handle memory as well. However, it does have unlocked multipliers, has a stronger than your average Clawhammer memory controller, and can handle higher voltages easier on it's 130nm process.
For $100, I'd buy the FX-53 and sell your 3500+ and end up being paid to use the FX.
