There are few 14" laptops I consider "gamers" (even those billed as gamers) but you might check out this link
http/www.xoticpc.com/custom-gaming-laptops-notebooks-laptops-ct-95_51_147.html I will suggest checking out the 15.6" models also as they can provide better cooling for a more potent graphics card like this model
http/www.xoticpc.com/sager-np8265s-clevo-p150sm-p-6200.html which features either the 780M or the 8970M (which are the top of the line mobile graphics) which is still in your budget and exceeds your weight target by very little.
Here's what I would do with that budget at XoticPC - starting with the 15" Sager/Clevo model I linked (base price $1454), customize with the following
1) Change CPU to: 4th Generation Intel® Haswell Core™ i7-4800MQ (2.7GHz - 3.7GHz, 6MB Intel® Smart Cache) (SKU – SPU202) ( + 185 )
2) Add: 120GB Crucial M5 mSATA SSD - Preconfigured as an OS Drive ( Operating System – Drive C: ) ( + 150 )
3) Add: Windows 7 Home Premium 64-Bit (64&32-Bit CD Included (Supports up to 16GB of RAM)) + MS Office 2013 Trial ( + 95 )
Total of $1921 without discount (or more customization if wanted)
