Good evening! So I currently have kind of a old rig and I think I'm gonna start upgrading it slowly one component at a time And I wanna start with the GPU, atm I have a sapphire 4670 512mb card, I did some research and found the 6670, is it the same 4670 with a few improvements? Is it worth it? What would you recommend me? I have a $130-140 budget and I want it with as little power consumption as possible. I play at 1360x768 @ medium/high settings. Tokio.
