I know buying a desktop will be cheaper, buying seperate parts even moreso, but I don't have space for a desk and with the added costs of a moniter, keyboard/mouse, desk, chair etc. it could probably even end up with a laptop being the cheaper option, not to mention saving me from the stress of putting a computer together. 

My budget is around £500 ($800/600 euros), I can go a little above but would obviously prefer to go a little below, the laptop has to be able to run Civilization V at medium settings smoothly. 

The best I could find was this: 

i7 - 2630m (QC @ 2ghz)

GT 540m - 1gb ded RAM

6gb RAM

This was found on ebay though, which is slightly risky to me. I don't really know many sites or shops that have good deals on laptops, so if any of you guys could help me find one or recommend some sites, I'd appreciate it :)

Update: I am 99.9% sure I'm getting this: 

- AMD QC A6-3430MX 1.7GHz (overclocks to 2.5 I think)

- 8GB RAM + 1TB HDD

- HD 6520G + 7670M Dual GPU 1gb ddr3

For £570

Update 2: 0.1% chance of me changing my mind according to my last update, and I did. Specs of the laptop I got are in my sig. Very happy with it :)

I have an Alienware M14x and man is that thing a beast that I can still tote around. 2720 QC 2.20 Ghz, 6gb of RAM and bunch of other stuff you can look up

Way too much for me, almost double my budget

AMD Llano 4C + 6490M,  £429

I can't find anything Intel + discrete graphics for under £500. If it was £600 then yes but looks like AMD is your only choice. Intel integrated graphics don't play Civ V well from what I can find.

Thanks, this is what I'll get unless I find something better :)

OK, looks like the 6490M gets 20fps on Civ V low settings. 

So, what you're asking for is basically impossible.

Alienware = over expensive  weird looking PCs that has the same specs as ones that are third it's price. 

whoever buy's them is a tool , or just want to throw away their money.

i recommend getting a desktop, cheaper, and easier to upgrade, but i f you insist on getting on, get a 8 GB ram one not 6.

The graphics card will be a much more limiting factor than the RAM at that price.

I just found this:

For £399, which will definitely play Civ 5 on medium settings nicely, so not impossible ;) Thanks for the suggestion though, I wouldn't of found this one without the link you gave me.
