why the hell would you go to best buy? computer parts are overpriced there. youre pretty much an idiot if you go to a store to buy computer parts anyways (excluding microcenter)
just order online, cheaper prices, and just easier
and how much are you willing to spend?
How do you find specs?
I mean I don't even know how
press windows button+r, type in dxdiag, screenshot the first 2 tabs
