Yeah that looks good, EVGA is pretty decent and at least their RMA process is really good. Plus it's a good price.
Just go for the 4GB, you'll be unlikely to go over that even at 1440p. My 470 is 8GB, and only fills up when I'm modelling/rendering. Otherwise it just doesn't happen, you're more likely to run out of GPU power than memory.

oh ok, ill give it a try.
 
Thanks for the efford 

It has 3x 6+2 pin connectors, and XFX makes good power supplies. 
 
It's a Tier 3 power supply rather than the Tier 5/6 that were considered earlier.

That sucks. Either way, the VS450 and the 450B don't have enough connectors. 

Yeah I know  I was half joking. 

Molex is a bad idea for powering a GPU because it stresses the rails that were meant for low demand things like fans. 

Molex?  I didn't notice that part.

No, its not a great idea. the EVGA 450b only has x1 6+2 connector, you need 2 in total for an RX480 and the adapter. 

What about a corsair CX450M? 

The 480 would be your best bet here. I'm not sure 100% how well the EXP GDC works but it would outperform anything else on the list. 
You should not bottleneck because you have 4 cores.

At that pricepoint I'd say a 1060 is probably better, with the 480 as a close second. Depends on what sort of features you're looking for (NVIDIA has a lot of stuff like GameStream and ShadowPlay).

People usual tell nvidia have better compatibility. Not sure if u can use internal display with amd, think u can with nvidia
 
 

yes but you won't need it. that is for switching between GPUs in you laptop
