Hi there and thanks for reading this, anyways I have been looking for a decent video card for moderate gaming and needed help selecting one that is compatible with my power supply and good enough to work with this cpu without bottle-necking.
AMD Phenom II X4 955 Black Edition (125 watt) with an Antec Kuhler 620 closed water cooler
2x of Ballistix Sport series 4gb Ram PC10600 1333MHZ in dual channel
Asus M5a78L-M LX Plus (Only has 1 PCI-E 16 slot)
Cooler Master Elite 350 System case that included a 500 watt power supply that claims 20amps on the 12v rail
OS: Windows 7 Ultimate (64 bit)
Also whats a good pci-expansion slot fan since I want to make sure the graphic card will run cool. So far my guesses for an optimal card for my type of gaming would be the GTX 650 or the HD 7770, which is the better of those two?
Does any of those power supplies have a fan on the bottom, my computer case needs a top mount power supply, also is there anything wrong with installing it upside down (not that mine is installed upside down but was just wondering)
