Recommended spec for mid level gaming.....

Hi Guy's was wondering if you could help?

I have been looking into purchasing a refurbed laptop, with the main purpose of playing Final Fantasy XIV on the go onc it comes out. I have had a look at the recommended system spec (below) and it seem's montrous no to mention expensive.

Operating System Windows 7 32-bit / 64-bit *
Processor Intel® Core™ i7 (2.66 GHz) or faster
Memory 4 GB or more
Storage Install: 15 GB or more
Download: 6 GB or more
Video NVIDIA® GeForce® GTX 460 with 768 MB VRAM or equivalent
Sound DirectSound® compatible sound card (DirectX® 9.0c or higher)
Internet Broadband Internet connection
Resolution 1280 x 720 or higher; 32-bit
DirectX® DirectX® 9.0c
Controls Mouse, Keyboard, Gamepad


I am not worried about playing the game on high settings, I would be hapy to play at Medium to low (after all the PS3 version will be 720p max) so what I want to know is what would you recommend as an altenative and affordable option to the above specs?
After looking into this a little I am inclined to think an Intel Core i3 330M 2.5 ghz processor and a decent Radeon Graphics card (not sure which one) would suffice. Would I be right in thiking this?

Cheers
