Hey, little bit of graphics card help please :)

Hey guys so i just need some graphics card advice, I plan to purchase this machine here;
http://www.ebuyer.com/product/176495/
But i will also be buying a graphics card, though i dont know alot about them, i read the reviews on the site and found this;
ive checked and there are plenty of spare slots for upgrading, main one being a PCI-E x 16 slot
So i know its got that, but i also dont know what a good amount is now a days of vram, anyway the game i plan to be playing most often only requires these kinda specs to run well, obviously the better the card, the better im assuming the game will run;
GeForce 200 Budget: 210, GT 220, GT 240, GTS 250
GeForce 200 Standard: GTX 260, GTX 275
GeForce 200 Enthusiast: GTX 280, GTX 285, GTX 295

So can anyone put all this jargon together and pick me out a suitable card? ps, the game mentions no particular amount of vram needed.

Ok mr , i decided i should fork out a bit more and have found this, it has good reviews, but im concerned about physical size and power usage, also cooling and stuff? http://www.ebuyer.com/product/160748
So will that card be suitable for this PC that a user states; ‘ive checked and there are plenty of spare slots for upgrading, main one being a PCI-E x 16 slot’ Thanks
