I've been a fan of ASUS' ZenBook series since the UX32VD, which packed not only a good CPU and discrete GPU (in the form of the 620M), but had upgradeable RAM and hard drive. The UX31A and its ilk was more questionable with its proprietary and failure-prone SSDs, but ASUS seems to have learnt its lesson there. But let's focus on what we have today -- the UX303UB, which comes with a 2.5GHz i7, 940M GPU, 8GB RAM and a 256GB SSD -- all for less than $1300.
Normally the ultrabook sells for over $1600, but if you hit up Bing Lee's eBay store, grab the UX303UB and enter the code:
You'll get 20 per cent off, bringing the cost down to $1279.20. Which is about what I paid for my UX32VD in 2012, though this comes with an SSD (the UX32VD had a 500GB magnetic drive) and double the RAM.
It's also upgradeable, so should you want to bump the RAM to 12GB or snag more storage, you're free to do that.
The GeForce 940M isn't a powerhouse, but in the right hands, you should be able to play games from the last few years at medium settings and should handle anything older without issue.
If you can get to a Bing Lee outlet, you can choose to pick the notebook up, otherwise for $10, you can get it delivered.
