^ I believe it is the CPU holding you back then if that is the issue. If you lower the video settings quite a bit and there is really no difference, that means the CPU is holding you have no matter what your graphics card can put out.
what if you start to increase the graphics a little, is it about the same FPS? Have you tried to overclock you CPU at all. I believe BF3 likes speed over more cores.
When video settings are change and there is no apparent increase or decrease in graphical output, it is usually a CPU bottleneck. I would really recommend a CPU upgrade.
This is your motherboard if the above information is correct. In this link is a list of compatible CPU's. http://www.msi.com/product/mb/785GM-E65.html#/?div=CPUS...
I would recommend upgrading to a Phenom II x4 or x6. It would be a good choice for you at least to start. NewEgg has deals on them alot. Just get one that fits your budget, but watch for deals as I said. the Phenom II x4 955 is on sale alot, but it currently sold out. I'd shot for something over the 3.0 GHz speed. They do have this one though. It would give you a pretty decent performance increase in your system over all, with everything you do. http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Thank you very much for your help sir. I get my left over college funds next month so I'll be able to purchase a new CPU.
Like I said. Look for a deal. I am sure you can get a good deal on a Phenom II x4 chip. They are still great CPU's to upgrade for people in your situation. For $100-$120 I bet you can find one for a deal. Worst case $140 will get you one and you can just drop it right in. Just make sure to get a retail version that comes with the AMD cooler. It is larger than your current OEM cooler if that is what you are running.
