So while playing battlefield 3, my 2100 gets to around 79% max. So this means my GPU is bottlenecking my system? I currently have a single 6850, and am looking to soon upgrade to 2. So would upgrading to a 2500k be needed? I don't want to see any biased answers, illegitimate reasons that don't even exist or any of that nonsense. The reason I am not waiting till ivy bridge is mainly because the 3770k is only 9% better than a 2600k, and at that time the sandy bridge CPUs will obviously drop.
