I am thinking of getting another HD 7850 GPU for crossfire. I have i5 2400 CPU. Will I have bottleneck problems? I have 750W PSU. The games I plan to run are BF3 and GW2. The reason for the crossfire is I really enjoy WvW and now they took off the culling I would like to have the settings on max or near max. The resolution will be 1080p and 2gb for the cards. Small chance of an upgrade to the resolution.

You should not have any problem with a bottleneck with the CPU. The issue with those titles are GPU centered and not around the CPU.

You are approaching the limit on the wattage for your PSU with this plan, and 850 W + would have a better safety margin.

The i5 2400 is still a very capable CPU. You shouldn't have any issues.

As you can see from this link:http://www.tomshardware.com/reviews/gaming-cpu-review-overclock,3106-5.html the 2400 is still listed as a tier 1 CPU.

Your power supply will be plenty as long as it is from a reputable brand and has the correct connectors.

A quality 750 is fine for crossfire 7850's. Actual usage from the PC side will probably be in the 350 or 375 watt range for that setup. So at 85% efficient that puts it about 410 - 440 from the wall or so.
