I recently bought a new laptop. Below your budget, but anyway…
I ended up getting a 17.3″ Acer laptop from Acer direct. I think it’s a 5750. It’s an i5 with 4gb of RAM (hmmm, might be 6) and a 750 FB hdd. It cost £530 but has since gone up to £550.
I got it as I wanted a larger, hi-res screen than the standard 15.6″ screens for photo editing and possibly Solidworks.
I’m very please with it so far – there was some crap software on there that I uninstalled, demo stuff like Norton backup & McAfee AV. I installed Microsoft Security Essentials and it seems really good so far.
Acer direct were good to deal with & sent it out quickly. I’ve only had it about a month, so can’t really comment on reliability. It’s also pretty large because of that screen.
Most important things to decide what you want it for & try to decide on a spec. Otherwise you will go rind and round in circles looking at dozens of laptops that are very similar…
Hopefully now someone will be along to rubbish everything I’ve written & kick off a few more ideas for you.
Oh…one last thing. It isn’t in the description, but the laptop I got has 1 usb 3 port.
This is it…
