Looking to build an inexpensive Gaming Computer to run my golf simulator. I have a stock acer x1420g that I am looking to upgrade the processor and GPU, I understand that I will have to move the internal componants into a different case with a better PSU. looking at Amd's website I see that the Athlon II X4 645 and the Phenom IIX6 1090T use the same AM3 Socket are they interchangeable or do I need to look at other options. Running the golf simulator is all it will be doing. The Simulator software is The Golf Club just for reference Thanks in advance
