The situation is that modern games are once again poking me to upgrade, and I'm wondering what would be most performance enhancing area to upgrade. I recently bought Bad Company 2 to play with my clanmates, and lo and behold, my mid-high PC is no longer mid-high. I find myself running at native resolution (1280x1024) in DX9 mode with all the graphical settings on low to stay above 30 FPS. The game is playable like this, but not as purdy as it could be.
My current system:
OS: Windows 7 Professional 64-bit
What I've considered thus far: Buying an AMD Phenom II X2 550 Black Edition dual core, and attempting to unlock the two other cores. I know this isn't a sure-success, but from what I've seen my mobo has been pretty good with it. Buying 2x 2GB of 1066 ram. This would run me about $100 I think. My ram might be bottlenecking my computer at the moment, I'm not sure. Buying a new graphics card. I really haven't kept up on the budget market, so I'm not sure what the best choice would be here.
What part could I replace for under $200 to get the best performance upgrade?
