Pros: This is perfect for budget builds for almost any setup up, games and otherwise. This unlocked stable for me (bumped the voltage a step just to ensure it get the power it needed) 4 cores running prime95 overnight with no errors. When i woke up the cpu temps were at 46c full load on corsair a70 (that's with the inculded paste, better temps with better paste of course). pretty amazing. Make sure to turn cool n quiet off to prevent a crash when going from full load prime95 to nothing (has to do with voltage/vdroop)

Cons: It's out of stock and i want another!

Overall Review: Wish it came in better package since i had a few bent pins (bending them back was easy enough).

Pros: It's AMD, it's a Phenom II, it has 3 usable cores at 2.8Ghz each, and it has L3 Cache. This is all 100% ensured, and true. However, in some cases, you could easily make it a 3.0Ghz+, quad-core CPU without hassle. If this goes on sale, and you want a cheap, efficient CPU, and (if like me) want a little risk in your buy (unlocking the CPU of course), go for this CPU.

Cons: Only a 30 day warranty, that doesn't cover a damaged CPU. So don't go insane and overvolt to 2.0V without a heatsink and expect to get a new CPU for free :p

Overall Review: I unlocked mine to a Phenom II X4 20 (that is what CPU-Z reports), and kept my speeds and voltage stock (2.8Ghz at 1.3V). After some messing around, I can get up to 3.3Ghz on all 4 cores without touching the voltage. Also, at stock speeds, 1.3V might even be a tiny bit much, even 1.2V might be enough, but you would have to find out :p Also, a Logistic's AMD CPU cooler (some $25 blue fan cooler) keeps my CPU around 30-40C (50C on full load), but as long as it is below the danger temp of 60C, it's all good. WEI reports 6.7 (X3 stock speed/volt) and 7.2 (X4 stock speed/volt) also.

Pros: OC'd to 3.2GHz right away, runs perfect. Runs under 40C with Coolermaster TX3 in an Antec 600 case.

Cons: None

Overall Review: I was worried about the shipping packaging from other reviews. Mine came in a taped clamshell, wrapped in bubble wrap that was securely taped, in a box packed with paper. UPS would have had to run it over to hurt it. Newegg fixed that problem.

Pros: I made my computer rebuild based upon a build guide from the folks at anantech for a mid range AMD machine. Per those specs, I purchased the Gigabyte GA-MA790XT-UD4P board, the Heka Phenom II X3 720 Black Edition CPU, the Gskill Ripsaw F3-12800CL9D-4GBRL DDR3 1600 (PC3 12800) 2x2gb ram, the POWERCOLOR AX4850 1GBD3-PH Radeon HD 4850 1GB 256-bit GDDR3 PCI Express 2.0 x16 HDCP Ready CrossFireX Support (they recommended the 512k but for $10 more, got one gig, Video and Win 7 Pro -64. This board and CPU quickly unlocked the X3 into a Phenom II x4 BE 920 processor. To unlock, go into Bios, MB Intell Tweaker, set CPU voltage control to 1.400v (to power the 4th core), enter Advanc Clock Calibration, set EC Firmware to Hybrid, set Adv Clock Calib to All Cores, and Value of (all cores) to +4%. Then verify with CPUid that you now have a quad.

Cons: Make sure you plug power into ATX port and also the ATX_12v-2x4 or you will not get a post, beep, nadda. The ATX_12v-2x4 was hard to access once the CPU sink fan was in place. I have a huge case and I can imagine that those with smaller cases might be cramped to access the six inner sata ports. Guys, read the manual before you complain about dead boards, CPUs, etc. or the fact it does not work with nvidia graphics. It is an ATI graphic board because Gigabyte went with the best graphics manufacturer in the market right now to avoid other hassles.

Overall Review: Have not done much overclocking yet as still setting up my system software, but I am stable at DDR1333 with manual timing of 7-7-7-21-2T, per memtest 84 and primes 95. Use prime95 v25.9 build 4 to stress all 4 cores at the same time in 64 bit. With no overclocking, my Win Experience Index is 7.2 processor, 7.5 ram, 7.3 on graphic and gaming graphic. Be sure to download AMD overdrive.

Pros: Unlocked the fourth core out of box simply by enabling auto acc and unleashing. Did severe benchmark testing for 24 hours. Running like a champ.

Cons: No temperature readings when you unlock, but that's ok by me, my Corsair H50 keeps it plenty cool ;)

Overall Review: I guess I was lucky mine did unlock. Remember always that a processor should not be purchased assuming unlocking as a "feature", think of it as a possible bonus, but always assume the worst.

Pros: unlocked 4th core, not over clocking

Cons: huh?

Overall Review: Replaced a athlon X2, motherboard, and DDR2, 2g, on sons computer that had been on the bad side of a lightning strike, for 135.00. Biostar 880g+, this cpu, and 4 gig kigston ram. luv newegg and luv AMD. typing this on it now

Pros: Unlocked the 4th core using a Biostar TA880GU3+ MB. Biostar has some crazy "BiounlockKING" feature that is supposed to do this for you w/o touching the Bios, but this didn't work for me. Had to go into Bios settings and set OC to "Manual" mode, after which it gives you the status of each available core. Manually set core 3 to "Enable" (cores are labelled 0-3 for this proc) and saved. Win7 booted, immediately installed new drivers for a 4core AMD chip, reboot and away we go. I haven't driven this chip hard, and will not push any other settings until I see how stable this is, but am very pleased for the moment. I did read that Biostar boards are better at this than other brands. YMMV.

Cons: A free core? What's not to like?

Overall Review: Should play very nicely with Skyrim - that was the reason for the upgrade. Also added 8GB DDR3 memory and a HD6770 video card. Not state of the art, but then I've always spent around a hundred for video cards and usually get decent perf.

Pros: Powerful Inexpensive Cool and Quiet

Cons: Does not make cupcakes

Overall Review: I used this in a HTPC setup after trying some weak processors (Atom dual-core) that didn't do it for me. The X3 was probably overkill, but I'm so pleased with it, I wish I had done it the first time. The chip uses AMD's cool and Quiet technology which throttles back the processor when it's at idle or under low load -saves electricity and keeps heat to a minimum.
