Okay boys and girls i will be getting this tomorrow:
http://www.aria.co.uk/SuperSpecials/Other+products/Asus+UL30A-QX328V+13.3%22+Laptop+?productId=44093

Can some lovely people point out what games will work well with it? :)

I will be buying Total Annihilation + Kingdoms as i know they will both easily work on it. Already own Master of Orion 2 as well :)

Blood 1 + 2, both Duke Nukem games. What games do you prefer?

Honestly i will play literally anything, but i mostly prefer RPG and RTS.

Dungeons and dragons maybe?

It's a little hard to say with that Intel graphics chip. Most old games without 3D graphics will work but these Intel chips tend to lack certain features like Hardware Texture & Lighting as they're only really designed for video & hd video playback. GOG has the minimum specifications on the game pages. So you might want to check that out. The processor is the main bottleneck on that system as some older games are CPU/intensive and none of them support dual core. It's hard to tell how powerful the CPU is really as sometimes these 1.3ghz are equivalent with a 3ghz P4 but lack the cache size which sets them back.

You might get Neverwinter Nights going on it as that's pretty friendly and all the older games. Baldur's Gate, Icewind Dale,Planescape, Arcanum should work without a problem. If you can find a demo of Ground Control 2 to try out I highly recommend that RTS but you'll want to see if it runs smoothly first. I ran it without a hitch maxed out on my netbook. Heroes of Might & Magic 3 wil run fine, Caesar 3, Sacrifice (another rts I highly recommend.), Outcast, Giants: Citizen Kabuto, Tropico Reloaded, Shogo, Patrician 3. Any Point & Click Adventure games (with the possible exception of Still Life & In Cold Blood.)

There's also a brief list here of a few popular games which will work on your graphics chip, though they may not run smoothly with your processor (e.g The Sims 2 which is highly processor dependant): http://www.intel.com/support/graphics/intelg45/sb/CS-029498.htm

One Must Fall 2097. I play this with dosbox on my netbook. It's freeware and way underappreciated.

My netbook (Samsung N120) can handle Tom Clancy's Rainbow Six without any problems, but it can't run Duke Nukem 3D. That DN3D seems surprisingly heavy.
