I am buying a laptop and am stuck on two choices the HP Envy 15-j110tx and the Lenovo Z510, they are both costing me the same. The only difference between them is the CPU, but I have used the Lenovo and its Touchpad is really bad,moreover the matte finish is of the screen on the lenovo makes the display look dull too. Plz tell me as to what I should do? Will the CPU make a lot of difference while gaming and multi tasking. Both have 2GB Nvidia 740M. Plz i need to decide quickly.

The i7 has more cores, since it is a true 4 core, however the i5 has 4 logical cores. This means that the multicore performance of the i7 will be better. They both use the same power and have the same thermal ceiling, therefore they are the same here. The i5 however, has a 2.5Ghz stock clock rate, which rises to 3.1 in turboboost, whereas the i7 has a stock clock of 2.2Ghz, which rises to 3.2. Overall: I would go for the i7 (since my experience of intel turboboost is that it keeps it running at boost for 90% of the time - my i5-2450m is meant to run at 2.5, but spends most of its time running at 2.9 in boost - this is lower than its 3.1 maximum though). All of this depends on your useage, if you are using it for video processing or...

All of this depends on your useage, if you are using it for video processing or gaming, the more cores of the i7 will come up good, whereas for basic tasks (eg: word processing) the i5's higher clock and boost clock will come good, as i said though, the i7 for the same price as an i5, is a MUCH better deal - so go with the i7

also: i have a lenovo, and the tochpad is excellent and the screen is best for using in bright light, since the dullness causes it to not reflect, also Lenovo are often more reliable than HP
