Well, if you're not gaming, I don't think you'll need a high end GPU at all. What matters here is a good CPU, with preferably more than four cores (actually, not sure if more than four is needed for music production, it depends, but do not get less than four) and at least 4 gigs of ram and an SSD.
Simply put, I'd recommend
A Samsung evo 850
An at least four core CPU - If I'm not wrong, intel core CPU's are generally better, faster, check out the i5 and i7 series.
A budget GPU should be enough
4-8 gigs of ram
-I am no expert, if I am wrong, point it out-
My specs are:
HD 7870 (faster than a gtx 660, slower than a 760)
i7-2700k
8 gigs of ram
Samsung evo 850 256gig
-Some WD HDD 1tb
