As I posted above, you can buy a $303 Lenovo G505 at the Lenovo Outlet. Try this link;

The selection criteria is set to include only those systems with a graphics card. The laptop that I purchased for $303 a few weeks ago runs Sims 3 perfectly. My daughter downloaded the Sims 4 beta, and it also runs like a dream, no lags, and at high settings.
I had to sit on the site for 2 weeks to find the $303 refurbished A10-5750 with the Radeon 8650G GPU. I recommend going to the site between 8am and 10am on weekdays, especially Mondays because that's when they seem to add new systems that have been returned from the stores. 10 minutes ago I looked at the site and they had an AMD A8 quad core cpu plus a Radeon 7000 series gpu for $360. You'll certainly be able to run Sims 3 and Sims 4 beta on that machine, for less than $400.
Ignore those folks who tell you that you can't buy a Sims 3 laptop for under $400, they're incorrect. The Lenovo Outlet sells new, scratch and dent, and refurbished laptops.
In fact, they currently have a laptop selling for $612 with the following specs;
Part number: QB07737280-59RF0912
Processor: Intel® Core™ i7-4500U Processor (4M Cache, up to 3.00 GHz)
Operating system: Windows 8.1 Standard 64 - English
Display: 15.6" FHD (1920 X 1080) MultiTouch LED backlight w/720p HD Camera
Graphics: NVIDIA GeForce® GT 730M
Memory: 8 GB PC3-12800 DDR3L SDRAM 1600MHz SODIMM Memory
Hard Drive: 1 TB Hard Disk Drive, 5400rpm and 16 GB Micro Solid State Drive
Optical Drive: No Optical Included
$612 for that system? That's the craziest bargain for a top flight gaming laptop that should normally be selling for twice the price!
Try the above link - you have nothing to lose. The systems offer 1 year repairs optionally extended to 3 years if you choose.
Anyone who doesn't check out the Lenovo OutLet is going to pay probably double what they could pay with a little patience until just the right system appears.
Good Luck! To repeat, for $303 this laptop plays Sims 3 perfectly, no lags at all, plus it plays Sims 4 beta flawlessly with no wait times. I think that you'll be cheering Toms Hardware for finding you this link!
ps. they sell to the US only, as far as I know. But they have a good customer service department accessible via phone, online or email to help you if you encounter questions before you buy. Just call them and ask if they would be willing to ship to Holland. If not, then maybe they can give you the name of the EU Lenovo OutLet site.
