How does GTA 4 work on Lenovo Y510P?

How much fps will I get on high and ultra settings?
specs:
i7 4700mq @ 2.4 ghz
8 gb ddr3 ram
gt 755m 2 gb ddr5
win 8 64-bit

Added (1). Will Using a cooling pad solve the overheating problem?

Added (2). Is GT 755M 2gb enough for next 4-5 years gaming (in low settings with playable fps)?

I get about 40 fps on those settings. Not to mention the heating though!

Nice Laptop i wanted it, it should get a solid 50 if not then download a fps checker thing (Fraps) run it and go into gta 4 and it should be a green number at the top somewhere btw you should just get gta5 on pc when it comes out.
