Intel has come a long way with their integrated graphics core. The Intel HD 620 is roughly equal to the nVidia 920m at the very least. It is at least as powerful as any of AMD's integrated graphic core with the exception of the Radeon R7 (Bristol Ridge) integrated graphics core in the AMD's most powerful APU, the FX-9830P. That AMD integrated graphics core is estimated to be roughly equal to the nVidia 930m; but no benchmarks exists for it yet.
However, as indicated by
starscream27, you can find better bang for your buck if you were to purchase a laptop from an online store. The GTX 960m is a lot more powerful than any integrated graphics core including the Intel Iris Pro 580 which is currently the most powerful integrated graphics core with the performance close to the nVidia 945m.
If you like the MSI GL62 6QF-628 that
starscream27 recommended to you, then I recommend you buy it from Newegg instead since it is currently on sale for $699. On top of that you do not need to pay taxes on any purchase unless you live in a state where Newegg has infrastructure which is CA (headquarters) and TN / NJ (warehouses). Amazon will charge you tax regardless of the state you live in.
