The GeForce GT 750M is the better, faster option. Coupled with the i5 2.6 Ghz processor.
GeForce GT 735M 384 @ 575 - 889MHz - 64 Bit @ 1800 - 2000MHz
HD Graphics 4400 20 @ 200 - 1100MHz --? Bit
My suggestion- Lenovo Y510p
4th gen i7
Dual Graphics (-SLI-)
2 hardisks -1ssd
Might be slightly more than 800 eur
Either machine will run resolume with ease.
p.s. Your english is very good.
