Hello all, this is my first time posting so please let me know if there is more information that is needed.
This is my current system.
Mobo Gigabyte Technology co. EP45-UD3P
cpu intel core 2 duo E8400 @ 3.00GHz
Graphics AMD Radeon HD 6850
Memory 8192 MBytes DDR2(dunno what that means but I just copied what it said)
64 Bit windows 7
Monitor resolution is 1360 x 768

My problem is playing bf3 multiplayer. On medium or even low settings I get small but noticeable stutters. on a 64 player map with lots of explosions the lag is a little worse. I'm not looking to play the game at super awesome settings, I just want to be able to compete without dealing without the stutters or lag. The reason for posting this in CPU forums is because I looked at my task manager while playing multiplayer and I noticed the cpu usage was at 100%. Does this mean my cpu isn't good enough? I was hoping to avoid buying a new motherboard if this was the case so any help on what I could do would be great. Thanks

you would have to go to a good quad core cpu to eliminate the stutters in BF3 multiplayer. With a better cpu, you should be able to play on high settings with a 6850 at your monitors resolution

How does your system run on the single player version of the game?
OK?

it runs great on single player, high settings with no problem.
so I was checking on newegg and I must be confused on how to shop around for a new cpu. The motherboard I have is old and according to the websites details the socket type is LGA 775.
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

When searching for desktop cpu's I clicked the LGA 775 filter and only had 6 options to choose from. None of them said anything about quad core.

im a bit of a noob when it comes to making sure I select the correct cpu so any help would be very appreciated.

Your cpu is topping out and causing you a major bottleneck.

If you don't want to do a complete upgrade , I would suggest you look at a Core 2 Quad like the Q9650 or Qx9650, grab one off ebay, they are still kinda pricey for their age tho.
It will elleviate your bottleneck and will play perfectly, I had the same problem with my E8500, so I picked up a QX9650 and overclocked it, problem was solved.

It's your CPU - your single player session pretty much confirmed that.

Nothing on newegg is better than what you have.
Are you ok with a used but tested C2Q CPU?

BF3 SP uses as many shiny DX11 effects as it can, which makes it stress the GPU much more then the CPU. In MP however, BF3 is VERY hard on CPU's, and fact is, a C2D simply isn't enough.

While a new SB based CPU would be a major upgrade, if you can find a cheap 8000/9000 series C2Q [assuming mobo support], that would be a cheaper short term upgrade.

if you think it will help I suppose so. I went into this problem initially thinking I would need to get a new cpu. I didnt realize the type of chip socket on my motherboard was outdated. Do you think overclocking would help? I would need to look up how to do it but im sure it's not that difficult.

Unless you get a bargain used Core 2 Quad CPU - you might end up spending not too much more getting a better Sandy Bridge quad, new motherboard and DDR3 RAM.

Did you have a budget limit in mind?

Thanks so much for the help =)

Since I was just initially thinking I would buy a new cpu I was only looking at spending no more than $200. maybe I should just put some money away and update everything like you mentioned.

wow that article is helpful thanks! no it isn't overclocked. there looks to be a few core2quads that arent too bad for my price range. I may just get one of those.

Your EP45-UD3P motherboard is known to be a good overclocker.
Get a good deal on a C2Q, a CPU cooler and you should notice a big improvement.
