i found this emachines desktop at bestbuy and was wondering if it is a good gaming computer and good for upgrading. it has 1 available pcie port for a graphics card. but i was wondering about the powersupply would i have to replace it or would it be powerful enough. and does emachines do the same thing as dell does with their powersupplies or will any powersupply work. also is the socket 754 or 939?
