BigDeep :
So the graphics will be better and the processor as well? how long you reckon this build will last me ? Thanks for answer.
Until one of the components wears out.
But seriously, if you have a motherboard with an AM3+ socket, you can always upgrade the processor to one of the newer FX CPUs. If that board has the older AM3 socket, you are stuck with what you have. The last processor line for the AM3 socket was the Phenom II X4 and X6 line.
Of course you can still upgrade the gfx card. But you wouldn't want to go much beyond the GTX 660 class cards or you will run into CPU bottleneck. The card may be able to game faster, but the Phenom II X4 won't be able to keep up.
And no, I didn't say the Phenom II X4 was better than the i7-2670QM. It is hard to compare a mobile processor with a desktop processor. The Intel CPU is definitely newer and faster. But it doesn't have the support structure around it to compete with the Phenom II in the desktop.
