I am thinking of buying a laptop for university work and some gaming. I preferably want to spend around £700 or less - I know this won't buy me much, but I want to see what I can do with that amount.

At the moment, I'm looking at a laptop with the GT 650M (2gb ddr3). I've heard that this is roughly the bare minimum you can use for a gaming laptop. I'd use it with 8gb of RAM and a 2.6 or 2.7 GHz CPU (dual core, i5 3230M or 3340M). I also have the choice of choosing a quad core i7 (3630QM, 2.4 Ghz), but I'm not going for it because I've heard: a) hyper-threading is not widely used in games as of yet, b) the 650M will bottleneck it anyway and c) it's more expensive.

Assuming that I can't upgrade the GPU, my questions are:
1) What sort of games could I play with this, and at what graphics settings?

2) Would the fact that the card is ddr3 mean that it could never fully utilise its 2gb? Apologies if I'm completely mistaken with this.

3) Am I right in thinking that there is no point in using a quad-core i7 processor with such a weak GPU?

Any help would be much appreciated.

DDR5 is a faster config. That GPU with 1GB DDR5 plays BF3 on medium on a MBP

My wife has a Sony S13 that has a 640 LE in it. A 640 LE is just a downclocked 650, so a modded BIOS flash later and she now has a 650... She played Deus Ex and Portal 2 on it just fine.

How to: http://forum.notebookreview.com/sony/677079-sony-vaio-s-bios-mod-gt640m-le.html

Specs:
Sony Vaio S13 Premium Gold (2012)
i5-3210M (2.5 Ghz) | 8 GB DDR3 | 250 GB Samsung 840
GT 640M LE 2GB @ 1000 Mhz | 13.3" 1600x900 LED display


Sony also sells the S15 with a 1920*1080 IPS display for a little cheaper than the 13" model we have.

Yeah try and look for something with GDDR5 memory. 2 GB of DDR3 VRAM is an example of OEMs overloading mediocrity to pass it off as something great.

Agreed. However, the GDDR5 units are quite hard to find unless you are looking at a larger and heavier desktop replacement/gaming laptop. Power and heat are hallmarks of GDDR5 comapred to DDR3.

Unfortunately, the site I'm using (PC Specialist) only offers the DDR3 version. How much of a hit to performance would the DDR3 receive compared to the GDDR5? I'd like to keep power consumption and heat output to a minimum, so I'd probably stick with the DDR3 if the performance isn't significantly affected.
