Hey guys. I'm thinking about upgrading my graphics card. I want a beefy one that will last me a long time. My computer model is a HP Pavilion A6130.uk I know I will need a new PSU to be able to run a beefy GPU and i think I might upgrade my CPU too a quad core i7 processor. The thing is I don't know if i can swap out my computers componants for other bits i buy? And if I can, what graphics card would you recommend me buying to be able to play crysis 2 on full graphics on a big res And what PSU do you recommend me buying?
