I think the E6750 is a very good choice. The performance of games is most directly related to the power of the vga card. Look at the new 8800GT, or possibly the higher powered version rumored for december before spending more on the cpu. Very few games are cpu bound with a good vga card, and even fewer can use more than two cores. Flight simulator X might be the exception. If you will build after the first of the year, wait for the affordable penryn processors to launch.
