    Should I expect much difference between performance of these cards in today's games? And the 750M will be combined with an i5-3230M, the 650M with an i7-3630QM.

    GT 650M GDDR5 with the i7 for sure. It can easily be pushed past a 750M GDDR5. Check my sig for an idea. I'd be able to push it even further without SLI.

    2nd config will be better overall... The 1st one will be due to the i3...

    Get the 650M/i7 combo, it beats the other configuration hands down. Not only is the i7 vastly superior to the i5, the GDDR5 equipped 650M can easily overclock to match 750M or even 755M levels. Never go with DDR3 on a GPU, that tech is outdated.

    Hm, I think I came across a laptop where it had a GTX 850M or 840M paired with DDR3. Don't remember the model name, but that was a deal breaker.

    Thanks for your replies. If I can get the budget all sorted out, then will go for the i7/650M for sure.

    W650SJ has a 850M DDR3 - but it's still miles ahead of the 750M DDR3 or DDR5.

    Hmmm I sure have made my point more clear. Don't get DDR3 if all things equal there is a GDDR5 equivalent. That said if a vastly superior card has DDR3, get it. It really takes proper research before you can make a decision like that.

    Just to be clear on one point, does a higher clock speed not compensate for GDDR3 memory?

    No because GDDR5 memeory is 4 times as fast clock for clock compared to DDR3...i.e 1000MHz GDDR5 = 4000MHz DDR3 ;)

    Pretty much this. The card with DDR3 would have to be far superior to the GDDR5 card. Such as the 650m vs 860m.

    Nope GDDR5 is quad-pumped instead of dual-pumped like DDR3 and other DDR, so it's double the bandwidth at the same clock speed and bus width, e.g. 128-bit GDDR5 @ 1 GHz = 128-bit DDR3 @ 2 GHz or 256-bit DDR3 @ 1 GHz.
