I am very interested in trying to get in to computer gaming but unfortunately my computer will not play much of anything the way that it is (even the original crysis on medium settings is too much for my computer). So I was wondering what kind of graphics card would work well with my computer. The information I found online said that my computer has an internal power supply of 250w (100-240V), a N-Alvorix-RS880-uATX (Alvorix) motherboard, AMD Phenom II X4 840T Processor and these expansion slots (1 PCI Express x16 slot for graphics card, 3 PCI Express x1 slots, 1 PCI Express x1 minicard slot). I have no idea what any of this means or really how to figure out what, if any new graphics cards would work for my computer, and would I would very much appreciate any help. I would also be thankful for any other suggestions on how to improve my computer for gaming. Thank-you.
