ive been looking at buying a laptop with a gt 630m to play games like Minecraft, BF3, Skyrim, TF2, Portal 2, Borderlands 2, etc. on med/high settings with ~28fps. ive looked on YouTube for game play with these games on the card but almost all of them feature a the 630m with 2gb VRAM but the hp dv6t-7000 only allows it to be customized with the 630m 1gb or get the 650m 2gb for 25USD (which i will chose if there's a good sale because in order to upgrade to the 650m i also have to upgrade the processor from the i5-2450m to i5-3210m which makes it about a 70USD upgrade overall). I'd like to know if there's a huge performance/graphical capability drop from not have 2gb of VRAM in the 630m. also I'd like to know just how big is the margin of performance between the 650m and 630m like if (theoretically) the GT 630m (regardless of ram) gets 30fps on skyrim high setting 720p but the 650m gets 80fps on same settings.
