I am running a fairly old desktop by today's standards, (2 years old) and am wondering if it is worth upgrading or just buying a new desktop all together. I have currently in my tower: Intel Core i7 processor 870 4 GB DDR3 NVIDIA GeForce GT320 1024MB graphic card I was thinking of upgrading the graphics card and Ram, but unsure what to buy and if it is even worth upgrading at this point. Any thoughts on this?
