i7-3630QM is used in Laptops but not in desktop...
Because the i7-3630QM has pins onto bottom where it connects to the CPU socket (PGA, pin grid aray), on standard CPU its flat LGA(Land grid aray),(Unless you're amd).
Only mod that is currently working from laptop soldered CPU to Dekstop is currently 1150.

If you wind I7-3570 (Non K) for quite cheap I would go for it,
but what did make you go for an upgrade if i may ask?
