I have recently purchased Civilization 5 and my computer cannot run it due to my graphics card. I wish to purchase a new one but I am completely lost on figuring out how to find a good, and still compatible card for my computer. All I can really help with is:
- I have a NVIDIA GeForce 7100 Graphics Card Rev. A2
- My motherboard is manufactured by Foxconn (Model Irvine)
- My southbridge is NVIDIA nForce 630i.
That's about it... I am NOT a very good technology guy, but I'll do my best :). Also, I don't know how to check my power supply and I'm aware that it is important, but I would do it gracefully if anyone could help me out. Thanks guys :)!
