Either way, NH-D14 will cool the chip, i5 or FX ( i will return to overclocking later if i buy locked i5 now ). i5 is significantly better on power too, and i presum in gaming scenarios. I also think that FX 6300 @ 4.5 Ghz is on pair with i5 i n general on games but with much more power draw. So is it worth to swap FX 8120 for i5 3330 ???
Itomic, I missed this post amongst all the bickering not related to your decision, and I played a big part in making your thread confusing, so I want to apologize.
I didn't realize earlier that you could get a straight swap without spending any money for the i5. That makes upgrading to the i5-3330 a good gaming upgrade. But if you can get an fx-6300 for the same amount you can sell your fx-8120 for, that is also a good upgrade. And you're right that, in general, the fx-6300 & that i5 will perform about even.
BUT, while on paper either upgrade is good, looking at the specs for your computer I see you have an LC Power Green Power 560w. This is one of those units which lies somewhat about its true wattage capacity but is not otherwise terrible quality (according to some google searches). As a result, I'm hesitant to suggest a heavy overclock on the fx-6300 for fear of stressing your power supply. Currently you say your fx-8120 is overclocked to 4.0 ghz, so if you're stable and don't have problems now, you should at least have some overclocking headroom on the fx-6300. But you might be better off with the i5-3330 because a) you don't have to put any money in and b) you'll have no worries on the power front.
Sorry I couldn't be more certain about what is the right choice! Personally, I'd probably go for the i5-3330, especially if you think your fx-8120 will sell for less than the cost of the fx-6300. But if you like to tinker and upgrade a lot and would change out your processor again in a year or so when the new AMD processors come out, there's a good argument for keeping your current motherboard. The good news is both choices are upgrades.
Edit: Finally found a good review of the LC 6560GP3 @ tomshardware.de:
According to google translate your PSU can be considered a quality 450w model, but not really a 560w model. This doesn't really change my recommendation above. A quality 450w system is borderline for an overclocked fx-6300 - so you might not be able to overclock very high. But it's tough to be certain.Edited by MisterFred - 12/30/12 at 9:49pm
