I just bought my 1st computer a month ago, now realizing it is shit, im trying to upgrade it anyway possible. I plan on buying more RAM and a new graphics card, but i'm not fully aware of certain compatibility issues, and other problems. Such as the graphics card I'm currently looking at says GDDR5 and I have a DDR3, so im not sure if that even matters since im upgrading, or if my motherboard can even handle it. I don't wish to buy a completely new PC right now so any advice about upgrading this would be helpful. Like I said, i'm not sure if any of the stuff i'm thinking about buying will even work, so anything is helpful. Please Help, Thank You
