Hmm,okay. I'll try it on my mom's desktop. Thanks,guys.

Well,at least I can finally say that I've played EB now.

BTW,I know I've been involved in that EB2 / SecuRom debate,but I hope you guys aren't holding that against me. It would really take a load off my mind to know for sure.
Vaios tend to be fairly high performance yes...for a laptop. In general though laptops will never be as powerful, components will always be nerfed to preserve battery life and space. It is possible to get laptops that can quite competently play most modern games, however you'll be paying through the nose.

You mentioned getting a 531S. I would advise against this, a quick google reveals these specs:
AMD Sempron 3600+
NVIDIA GeForce 6150

In one word, nasty, especially for that price. 3.6Ghz is very slow for the money you're paying, and the 6150 is ridiculously outdated. As a benchmark, I was able to pickup a rig with a 5.6Ghz Athlon cpu, 2gb of ram and a Geforce 8600 (not a brilliant card but it'll do on a budget) for perhaps fifty pounds more about six months ago. In short that rig looks very pretty, but inside its a dog.
With three or four hundred pounds (or more) you should be looking at at least 5-6Ghz, a couple of gigs of ram and hopefully a 8800GT or 8800GTS if you shop around.
