Best processor I can upgrade to is the Phenom II X4 940, as my motherboard is a AM2+ socket, not AM3. Also I am pretty sure I am going to upgrade graphics, to a ATI 4870 with 2GB GDDR5. Sounds like a lot but I have been running out of ram sometimes as the graphics uses a gig of the DRAM. I my upgrade processors to the 940, but I was going to get the new Logitech G940, so I think I will hold off on the processor. Also you seem to know a lot about systems so if I did change CPU's would it be straight forward, or would I also need to update BIOS, and other stuff?-Thanks, GE90110B
