Which laptop CPU should I get for gaming?

I don't want to spend like a crap load on the cpu's so not the best one... I just want like one that is going to work pretty good with an ATI Radeon 5870.

Like, what is general consensus on buying a processor? My cousin said sometimes it's good to get the newest generation even if it's the cheapest of the newer ones, but I dunno?

Thanks in advance guys! I really appreciate your time.

More about which laptop gaming
  1. Between those,IMO i7 740QM has the best price/performance ratio, because there are some games/apps that are multi-threaded and benefit from a quad core CPU.
  2. according to me core i5 540M cause it's a 32nm... and cheap too.. or i7 620M...
  3. But its dual core, and since upgrading the laptops CPU is more difficult than desktops(because finding mobile CPUs isn't as easy as desktops and also because it voids the warranty),so IMO its better to go with a quad core.
  4. +1 for a quadcore.
  5. +1 for the quad as well (since the turbo is 9/6/1/1) allowing good usage among many thread counts
  6. +1 for the 740 for power since it can use ddr3 @ 1333 memory and the 540 can't (stock)
