Pros: It's E8400, so easy to overclock, and it's the best for gaming, clock speed is king in games so quadcore has no use to me. 50 cheaper than the retail (which isn't even in stock yet).

Cons: 1 year warranty instead of 3, and no HS/F, but none of that matters since most people who get this chip will OC anyways, requiring aftermarket cooler (I got the Arctic Freezer Pro 7) and voiding warranty. Chips either die on the first day or live on for years, hit and miss really. So no cons IMO.

Overall Review: Running EVGA 780i 2 x 2 GB DDR2 1066 g.skill 150 GB 10,000 RPM WD EVGA 8800 GTS 512 MB PC Power & Cooling 750w Antec P182

Pros: Just got it today, had it overnighted and it came in 24 hours! i EASILY overclocked it to 3.4 using easytune 5 pro on my gigabyte board, temps are about 40c under full load and OC'ed(using rosewill heatpipes). Very fast proc, my encoding times are cut in half from my old Pentium D 920. Overall, it runs very cool, it overclocks like a dream, its 45nm, and its very fast.

Cons: Many programs dont have SSE4.1 instructions yet so its full potential cant be unlocked... yet. And my gigabyte DS3R had to have a Bios flash to support the chip, remember, you must flash the BIOS BEFORE you put the chip in.

Overall Review: E8400 @ 3.4, 3GB OCZ, Vista-Prem, gigabyte P35-DS3R F11, ATI X850XT.

Pros: IMO the best bargain to have come out of Intel in quite a while. $200 Gets you a Dual-Core 45nm Core2@3.0 which can easily go to 3.6 ON AIR! Simply pair up with DDR2800 and a Mobo rated to FSB 1600.

Cons: Supply, not demand, just the supply. I had to keep the page of the 8400 up and refreshed every 20 minutes until I was able to catch it in stock.

Overall Review: Part of a New build which will cost ~$1k and change to play Crysis at 1088*612 w/ Med/High settings and achieve fluid frame rates. (think averaging 50s in a game people settle for mid 20s...)

Pros: Extremely fast processor. I made the questionably backward jump from the Q6600 because I wasn't making much use of the two extra cores as I'm primarily a gamer/student. I have heard this overclocks to 4.2ghz and blah blah blah, but honestly, you aren't going to notice much of a difference at 3.8+ Another HUGE plus for me is the energy efficiency.. My total system idle power consumption with the Q6600 was just around 240W.. E8400 will cut that down to about 200W or less even.

Cons: Price is soooo unsteady. I bought this LAST NIGHT for 10 bucks more. What's the deal newegg?

Overall Review: People who plan on overclocking this to 4.5, don't get your hopes up. Because it's 45nm, it also means higher voltages are quite bad for this. I have heard to keep it below 1.4V or else you risk frying the chip or significantly reducing its life from years to even days. No matter how cool it may run under your heatsink, there is an electrical limit that you should be aware of.

Pros: Great little chip. Very stable @ 3.6 on stock voltage with air cooling.

Cons: None (besides being hard to find).

Overall Review: CoolerMaster Cosmos 1000, OCZ GameXStream 700W, Asus P5N-D, E8400 @ 3.6, Patriot Viper PC6400 4-4-4-12, CoolerMaster Hyper TX2 CPU Cooler, EVGA 8800GTS (G92) 512MB PCIe 2.0, 2x 74GB WD Rapters (RAID 0), Lite-On SATA DVD-ROM, Windows XP

Pros: Replaced a E6600 in an Asus P5e Wifi. Pretty impressive so far. Haven't run any major tests yet, just normal everyday stuff. Watts drawn at the wall have dropped about 10 watts at idle compared to the E6600.

Cons: Upgraded the bios before replacing the processor to get a bios that supported the 8400 and make sure everythign was stable. After replacing the processor the bios said failed overclock even though I wasn't. It acted kind of flaky at first so I just reset everything to default and rebooted and no more problems.

Overall Review: Replaced E6600 with the E8400. After turning the pc back on Vista Media Center was giving me a bunch of errors. After googling the errors I ended up deleting all of the files in C:\Program Data\microsoft\Windows\DRM and rebooting. The errors went away after that.

Pros: Very fast right out of the box and is very easy to OC

Cons: none

Overall Review: Paired up with Gigabyte GA-Ep35C-DSR3 @ 3.6 GHz on air with ease and 4 gigs of crucial balistix. I would recommend to anyone.

Pros: Fast,fast,fast. 199.00 6mb cache 3ghz stock.

Cons: none

Overall Review: For me this proc is like fine wine gets better with age. After an update from abit I almost got to 3.6 stock voltage everything. slowy I've been able to push it every day or so to get better clock speed in a nother week or so I might get 3.6 on all stock settings. Newegg is the best. Tiger who....
