can i run it? (medal of honor example)

Can you?

i7 can run almost anything...

Of course you can run it, if i can run it on Pentium 4 and 1 GB RAM then you can run it even on the integrated video card of that i7-4500U which is a beast.

Your new CPU will AUTO-overclock at 3 GHz the second you start the game. It's called "Turbo frequency" and it is auto activated whenever you play games or watch HD movies. The normal 1.8 GHz frequency is for power savings (low temperatures, longer battery life).

Try here. (I just guessed on the RAM).

Don't worry about that.

My CPU is Dual Core 2x2.6 GHz and I can run it on full graphics

The i7 4500U is hyperthreaded so technically, it's quad core

i have a pretty crappy laptop and worse spec than that and i can run skyrim and dmc just fine i think you will be fine as well.

If by Medal of Honor you mean the previous bundles 2010 version, you probably can.

I get a solid 15-20 fps on lowest possible settings with a Core 2 Duo 2.2GHZ and 1GB of VRAM, so you should be fine with that i7.

I ran MoH 2010 on my old Lenovo T500 which had something like a Core 2 Duo 1.7 Ghz, 256 or 512 VRAM, and 4 GB RAM. I doubt I maxed the settings but I don't think I played at lowest since I don't remember it looking to shabby.

You can, but why? It's a horrible, horrible game with extremely narrow FOV and a length of 4-5 hours.
