Hey guys, decided Im going to get a new GPU. Right now I'm debating between the 7870 and the 660, but am leaning towards the 660. (non ti) I know these would be considered midrange cards, but I want to make sure they would not be completely bottlenecked. My system specs are a i7 3770, 8gb ram, 600w, and what I'm guessing is a cheap motherboard. (it's a HP Pavilion). Would my motherboard potentially bottleneck this card?
