Recently I have been thinking about upgrading my processor, ram, and graphics card and I would like to know whether or not these will work. The current computer I have is a "HP Pavilion p6674y Magnesium Gray Edition" and the upgrades I have installed on it are a 800 watt Corsair power supply (GS800) and a AMD 7950 XFX graphics card. The upgrades I am wanting to install are 8 gigs of ram (Corsair), a "AMD A8-6600K Richland 4.3GHz Socket FM2 100W Quad-Core Desktop Processor AMD Radeon HD AD660KWOHLBOX", and a second 7950 so I can connect them together. Will this work with the current motherboard I have or with the current amount of power I have? (Also it is very likely I will have cooling problems so any tips on that would be appreciated)
