I know your system will be able to run Battlefield 3. If your system can run Black Ops then it can run battlefield 3. Nice system build you have there. How do you like the Sennheiser PC350? I'm getting the Xonar Xense for my new system build.
I'm curious what the new Ivy Bridge and P68 is all about. How do you like your Mushkin ram?
It's not a question of if I can run Battlefield 3, it's a question of if I can run it in a full 64 player server and be able to pull 60+ fps at all times. I demand fluid gameplay at all times, and I'm sure Battlefield 3 will have decent longevity with the amount of support DICE is saying they're going to give. I'm also considering getting a joystick for helicopter and jet operations.
I like my Sennheiser PC350. It's a durable build and has lasted the longest out of any headset I've ever bought. The microphone is high quality and there is never any problem with people hearing me clearly on voice chat. I use my headsets a lot and previous ones would usually fall apart within 6 months. The headset itself is comfortable, and the cups don't touch the ears but rather wrap around the ears so that you don't get irritation. I wear glasses and the headset doesn't bother me in the least. I've had my PC350 for about a year and a half, and recently the material that wraps around the ear pads has been flaking off. The headset itself is still comfortable, but this material sticks to skin and is quite annoying. I'll probably eventually buy a higher quality headset or headphones, and I'll definitely consider Sennheiser.
Ivy Bridge is a updated version of Sandy Bridge and should use the same 1155 socket. Intel is saying that there will be about a 20% performance boost over Sandy Bridge, and I'm sure it will overclock very well. I belong to an overclocking forum and it's not uncommon to see people with 4.8-5.0 ghz overclocks with the i7-2600k processor, on air! I haven't looked into P68 at all, as I'm not really looking to upgrade my processor and chipset until it becomes a bottleneck for gaming.
I really like Mushkin RAM, they have excellent support and I've used their RAM in several PCs over the years without any problems. Mushkin has nice performance RAM, which would be the Blackline, Redline, or Ridgeback series. I have a mild overclock on my RAM as a result of my CPU overclocking configuration, and it's running at 1643 mhz with stock timings. I haven't really messed with my memory too much but I bet I'd be able to push my memory even farther without problems. Lastly, I like how the Blackline and Redline series have low-profile heat spreaders(which work well), and are useful when mounting large heatsinks like my TRUE or a Silver Arrow/Noctua NH-D14.
