First off I desperately want to upgrade my CPU because I feel it's slowing down physics in some games, for example I get only 14fps in Railworks Train Sim 2012, I'm hoping that a quad core will be able to handle the physics better and give me a framerate boost.
Having a hard time deciding between GTX560 and 560Ti, the Ti is a little better but I'm not sure by how much, or whether it's worth the price, and whether my 550W PSU can handle it all. I definitely want a NVidia GPU because I think they're better and for games that make use of PhysX.
For RAM right now I have 2x2GB sticks in dual channel, if I get 4 sticks of the same RAM does dual-channel still work? And I'm not sure this upgrade is worth the bang, I don't see games using alot of RAM.
The case...well...my current case is held together by duct tape after I was doing some repairs to the headphone jack, I wanted to get it clean and also have more airflow and fans. Again hoping my 550 W PSU can handle 3 fans + lights + etc.
Thoughts? Suggestions? Criticism?
