Pros: This CPU IS A BEAST! I also have the AMD Brisbane 5400+ OCed at 3.3 GHz but this one runs circles around it. I OCed this one to 3.4 Ghz stable and i saw a 20%-30% gain in games than the Brisbane. Its the 1MBx2 cache that makes the difference over 512kbx2 cache of the Brisbane.

Cons: Ok this is a beast. You need to have a good cooler. I have this http://www.newegg.com/Product/Product.aspx?Item=N82E16835200025 and get 38C idle 55C full load at 1.55 Vcore. Make sure it dont go about 63C under load and you be ok mon. If you want to go higher than 3.4 GHz you are going to need good RAM cause it has locked multiplier.

Overall Review: I feel good inside about this CPU. :O

Pros: Boosted L2 cache over my old 4200+, boots Vista seconds faster, XP x64 in under a minute, love this thing. The L2 cache was the one thing that I was looking for, the speed was just a bonus for me since I play games a lot and they benefit more from the L2 than they do the processor speed, especially if the speed is already dual core over 2Ghz (like my old 4200+). I've seen framerate boosts and processing time boosts in pretty much everything that I do. Highly recommend this chip if you're still using an AM2 board..

Cons: Runs a lot hotter because it's 125w not 65w, but the triple TEC cooler I use could handle it easily. Need to watch the temps on the mobo after plugging one of these badboys in though, temps across the board went up 1-10c. Probably from the increase in speed, and the increase in ambient temp from this beast.

Overall Review: Get a good cooler, a stock AMD will get you by, if you're a desktop user, but if you're a gamer, get something a lot bigger, you'll need it.

Pros: The 6400+ is fast- 3.2GHz, I stably overclocked it at 3.4GHz, the 2MB L2 cache is a plus it's fairly inexpensive...

Cons: I upgraded from a 5200+ overclocked at 3.1ghz. At stock speed there was a small but noticeable improvement over the OC'd 5200+. I have it OC'd in my rig running at 3.4Ghz. I guess I expected to be able to get a bit higher than 3.4 (212x16) but it crashes every time. Also, for some reason my mobo's auto OC settings crash my rig every time (It works wonderfully with the other cpu's I've put in this board). I oc'd it manually- 212x16 w/ no voltage changes. The 6400+ does run pretty hot with a stock fan & heatsink. I would NOT OC it without a quality cooling solution. Had known that I would not get above 3.4Ghz I would have given more thought to paying the extra $$ for 2.5-2.6Ghz Quad.

Overall Review: Like I said above, a good cooling solution is a must, even if you're not OC'ing & have a well ventilated case!! For a SWEET, heatsink/fan combo I would recommend the >Arctic Cooling Freezer 64Pro< it works awesome!!- OC'd at 3.4GHz it idles ~33-36C. PLUS it's really inexpensive. I bought mine at a local store for $19, but I think Newegg sells 'em for around $12!!

Pros: Great performance. Great Price. Great upgrade form my +4200, & the extra L2 cache grants noticeable gains in CPU intensive applications.

Cons: Going from the energy efficient 65w to this 125w is gonna up the utility bill a pinch, but well worth the extra scratch.

Overall Review: This is my 2nd OEM cpu from Newegg and my 5th OEM product, plus an OpenBox item or 2, & I have yet to have a single problem with anything other than incompatible RAM for my buddies Dell laptop :-(which they RMA'd quickly, I might add:-). Seems Newegg puts effort into making sure we are being well served, even when not buying Top-dollar-Brand-new-in-the-box stuff. Never disappointed. gOEM !

Pros: Fast and awesome, actually runs pretty cool, super stable and running Vista 64 with zero problems

Cons: Kinda high wattage for a cpu but hey, it works

Overall Review: Intel needs to pay attention to how easy the heatsinks for these things are to install instead of their arcane design

Pros: Replaced my 5000+ BE. I've got the Asus m2n32 sli deluxe wifi mobo in my rig and its been the best board i've ever owned so far. I couldn't part with it yet and I didn't want to anny up the money to do a complete overall in my system so I just decided to upgrade to this baby. Even at stock settings I can tell a noticeable difference between this and my oc'ed 5000. It respondes a lot better and when i seemed to throw to much at the 5000 there was quite a bit of lag and it struggled. This thing just keeps chugging through everything I throw at it. The only time it have a problem is when I play crysis but thats more or less because of my graphics performance. Even though I can't play it at the highest settings this thing runs it smoothly for what my 9800gt is capable of with a 22" monitor and even after exiting the game it just keeps bouncing around like nothing happened.

Cons: Runs hot but to be expected. Its a 125 watt processor and if your expecting core 2 duo temps then good luck.

Overall Review: I'm someone that doesn't like the cold weather. And well I've got a faster computer and a heating device for my room so works out great for me =) Once I get another 9800gt for sli then ill be golden. With some arctic past and my zalman 9500 am2 heatsink it runs about 41 C idle and 50 C under load. Max temp for this thing is 63 so I've got some room to work with. I've got it at 3.31 at the moment and its 45 idle and 55 load under stress test. This proc, 9800gt, 2x1 gig ocz sli ready memory, antec 900 case (fans at max all day and night). This thing seems just as responsive as my brothers 3.8 e7300 machine and yet it loads windows faster and keeps puttering where his seems to hang sometimes. Happy to stick with the AMD guys =P

Pros: Fast, fast, fast! I read a lot of reviews about this chip running hot. I used the program "PC Probe" that came with the Asus mobo and the CPU runs at 36 C at idle and under the most load that I can give it under COD4, maxed-out settings, is 56 C. My case is rather cool though, I have 5 case fans. I don't consider 56 C too hot. There are games like Crysis that will test really test the CPU but COD4 is the best I can do for now. I have not over-clocked yet.

Cons: None, as usual I am really happy with NewEgg and with what I have purchase from them. One thing that I really love about Newegg is the product reviews. I would like to encourage everybody to leave product reviews because it is extremely helpful, it is one of the major reasons I keep coming back!

Overall Review: I scored 171 FPS, on Steam's video stress test with these components, AMD Athlon 64 X2 4600+ Windsor 2.4GHz CPU, ZOTAC ZT-88TES3P FCP GeForce 8800 GT 512MB Video Card, A-DATA 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 5-5-5-18 RAM, ASUS M3N78-EMH HDMI Mobo, COOLER MASTER eXtreme RP-500-PCAR 500W Power Supply, ARCTIC COOLING Freezer Pro 64 Fan....... I had to change out the Mobo because the ASUS M3N78-EMH HDMI doesn't support the 3.2GHz CPU to an ASUS M2N-E AM2 NVIDIA nForce 570 Ultra MCP Mobo and an AMD Athlon 64 X2 6400+ Windsor 3.2GHz CPU. My FPS went to 231, what an increase. I started out at 45 FPS using the on-board video.

Pros: As always, AMD CPU's are an easy upgrade. This of COURSE is THE fastest Athlon dual core, made. Yes, it's solid, and there's no load it won't make short work of. Gigabyte 790 FX DS5/ 8 Gb Patriot 800/ BFG 8800 video/750 watt PS/ three 750 WD Hd's. Not too shabby.

Cons: A little hotter than the 5000 I replace, but that's to be expected....so...Con?? not really.

Overall Review: Lesson learned: DDR2 1066 memory minimun requirement of a tri-core processor. Reason? Because 1066 wasn't made until after the dual core processor. You don't build todays cpu for tomorrows memory.
