The 650
The 650 is better than the 210 and both on the weak side whereas an i5 and an i7 are both on the high end. So the GPU will be the weak point in the combo, go for the strongest one of that, which is the i5 - 650 combo.
If the choice of these two is due to budget (and not because someone is actually offering you these specific two) you might actually want to scale down to an i3 and get an 750 or something higher still. For the same reasons mentioned above.
