according to the link, it's 1366 * 768. Should max it out pretty well. BTW, the mobile i7 is roughly equivalent to a desktop i5. I wouldn't try to downgrade it. This unit is future proofed on the processor, and at that res that graphics card is fine. If the price is right for you, go for it. looks like a decent deal to me.
compare mobile processors to other mobile processors, not mobile to desktop, and also, there is will be no noticeable performance difference on that resolution
