I removed the Devicelist as you requested.
I'm glad we finally got it working.
For a better gaming expierience i would first try reducing the "graphics quality" setting and disabling "Anti-Aliasing" in the games "advanced" graphics settings. You can play around with all graphics settings, until you get the best performance/quality compromise.
You get to the Menu by pressing the ESC Key. There you can change the settings or load/save.
If you want to play with the highest settings a new Graphics card should be enough.
There's a wide range of models and it depends on how much money you want to spend. Judging from your computers initial state i would assume you don't play 3D games a lot, therefore a card in the low or mid price range could be a good choice.
I can't really promise you which is the cheapest card that runs the games perfectly in your screens resolution with all settings set to highest. For that your best option is probably to ask other users in the BTTF Forum about their experiences with different graphics cards.
Just to name some cards at least, I think that the "Nvidia GeForce GTS 450" or "AMD Radeon HD 6670" might work well, probably even cheaper ones.
You might need a new power supply for some graphics cards too, but it's best to let the people who upgrade your computer deal with the details.
