I am looking to upgrade my CPU on my Dell XPS 410. I have a NVIDIA GTX 550 Ti graphics card and and still running low frames in some areas of WoW and so I figure I need to get a different CPU. I don't know how to determine whether or not a CPU is compatible. I have a 375W Power Supply and currently am on a 1.86gHZ Dual Core processor. I have 2GB of DDR2 RAM and am using ReadyBoost with some flash drives for an extra 10GB of memory. The computer has an Intel P965/G965 Chipset.
Also, is the CPU the bottleneck for sure?
