I built a new computer in early 2010 and it is still going strong. I am late on the scene of games and I'm cheap, so i'm still playing games that are at least a year old most several years old. Recently I found a few that will not play correctly because of my graphics card. I'm thinking about upgrading my graphics card so I can keep this computer going for another couple of years. After that if the computer is still good, I will use it in a MAME arcade machine. My current specs are: GIGABYTE GA-MA770T-UD3P AM3 AMD 770 ATX AMD Motherboard, I have a AMD Phenom(tm) II X4 3.1 ghz processor 8gb of ram and a GIGABYTE GV-R467ZL-1GI Radeon HD 4670 1GB 128-bit DDR3 PCI Express 2.0 x16, 8GB ram Windows 7. So I know I need PCI express 2.0 card, 3.0 will not make a difference to me correct? Im looking for a card in the $100 range is this one ok? http://www.newegg.com/Product/Product.aspx?Item=N82E16814102993 Any recommendations? My PSU is 400watts, will a new card be ok? Is there something about my computer that will not let me take advantage of a better graphics card? I assume the jump from a 4670 card to a 7770 crd will be siginifant even though they are both 1gb 128 bit cards?
