I have a stock Alienware x51 rig and it runs good, but I would like it to be better. it has an intel i3 3220 processor, 6gb ram and a NVidia gtx 660 video card. I believe I have an intel ivy bridge H61motherboard, but I don't know how to find that out precisely. I am thinking about either boosting the ram or getting a new processor. I would probably go with the intel i5 3570k because of price and cpuboss.com comparisons. What do you more knowledgeable people think?
