Summary: If your not planning on buying a graphics card I would suggest the 3245 or 3225 which have the hd4000 graphics. This is a great processor for a mid range gaming rig. If you're not spending over $200 on a graphics card this wont be a bottleneck.
Pros: 3.5ghz dual core hyperthreading! Great bang for the buck! 7.3 WEI 7 score! Easy installation
Summary: Installed the i3-3250 CPU on low cost TZ77A motherboard and got WEI of 7.3, 7.6, 4.9, 6,3, and 5.9. Works great with Windows-7 Professional and the XP mode. Purchased on sale, suggest you check the current prices of i3-3220, -3240, & -3250 since they are so close in performance. For a game system, suggest you use the newer Haswell socket-1150 CPU's and motherboards, so you can later on still upgrade the CPU.
Summary: Great CPU for the Price, and being the best i3 of its generation and all the generations prior I find minimal difference between a Haswell system and an Ivy Bridge system of this tier. Theres a lot of confusion surrounding the on-board graphics of these types of CPU's. In short if you don't want the on-board graphics then just pretend they aren't there.
Pros: -2nd Highest clock speed of any modern dual core CPU
Summary: I3 cpu, 3rd gen, is a great processor for the average business user. That being use of Office 2013, Win7, internet browsing, and a business application or two, such as QuickBooks, and a Cloud app. This type of user really doesn't need any more power than what this chip provides, especially when paired with 8gb of 1600 ddr 3 ram and a good ssd storage unit.
Pros: If you are building a small, home PC, this is what you want. Super fast, snappy Dual Core CPU. Low power and isn't too expensive! It's Intel. You can do alittle better with HD graphics, but if you have a video card, then this is perfect. Runs games really well too! Haven't had any problems with games.
Summary: If this was an unlocked CPU I'm very sure that it would blow away most core i5 and i7 systems in OC and frame rates in most games as many don't make very good use of more than two cores. I really wish Intel would make a K series of this without the graphics portion on the die.
Pros: I got this for my sister who plays WoW and Rift. She doesn't have tons of cash so I used this as the heart of her system and what a surprise. I was able to max out the graphics on her system in WoW. Now she doesn't have to play "Foggy WoW" as she called it.
