Gentlemen, we can rebuild it. We have the capability to make the world's first enhanced store. Steam will be that store. Better than it was before.
But would you recommend me to change my GTX 570 by a RX 480, if I told you I found a great price for it, and can't afford much more? I mean, would this upgrade make sense, keeping the rest of the set up?
Cause, at first, I thought I would need to change everything to get a decent performance for 1080p modern gaming (my GTX 570 is having though problems to deal with Doom, Dishonored 2 and Mafia 3 for example). If swapping a GTX 570 for a RX 480 can make things much better, by the price it was offered to me (I'm brazilian, the hardware prices here are all over the place but generally very expensive) I think it's worth it. I can think about changing the CPU and motherboard later if I gain a even better performance after swapping the GPU.
Going from a GTX 570 to an RX 480 should be a pretty big jump.
Additionally (since you posted your specs earlier) you would probably see quite a bit of performance increase and decreased loading times and such by replacing your HDD with an SSD. Just throwing that out there since it's usually something that's easily replaced and isn't typically dependent on your motherboard unless you're still on SATAII.
