Just last week i purchased the RC530 for $850
this notebook featured
750Gb HDD
6Gb RAM (4+2)
intel i7 2.0Ghz quad-core processor
1gb Nvidia GeForce GT540M dedicated memory/ graphics card
But the today i ran into the RF510 for $1000. The money is not a problem but i wanted to know if the extra $100 would deliver me a greater gaming experience.
This notebooks stats are as follows:
640Gb HDD
4Gb RAM (2+2)
intel i7 1.6Ghz quad-core processor

2gb Nvidia GeForce GT420M dedicated memory/ graphics card

Is the extra 1Gb dedicated graphics memory worth the sacrifice of HDD space, RAM and clock speed along with the extra $100 and trouble of returning the already bout one? How much will gaming differ and does anyone know how well these notebooks overall perform?

THANK YOU ALL IN ADVANCE I HOPE YOU CAN HELP!
