I'm sure this is a HP Pavilion dv7t Quad Edition, not the ENVY one.
Based on the assumption above, the graphics cards this laptop offers are either GT 630M 1 GB GDDR3 or GT 650M 2 GB GDDR5. Therefore, this laptop has GT 650M 2GB GDDR5 if I'm right about this laptop being Pavilion.
The only choice for 1TB of hdd for HP Pavilion dv7tqe would be 5400 rpm.
Full Specs info that is most likely wrong (But I tried and there's a chance for the whole thing to be right):
