I'd go with the 2011 platform, a couple extra features and native support for ivy bridge (1155 requires a bios update) and I would go for the i5 to save some cash because hyperthreading doesn't do anything for almost all games in performance.

Ram honestly on whatever day you are buying pick up the cheapest 1600mhz cl9 1.5v ram (maybe $40-45)
680, more performance less power consumption easy decision.
Buy Gigabyte [GV-N680OC-2GD] Gigabyte GeForce GTX 680 OC 1071MHZ 2GB 6.0GHZ GDDR5 2xDVI HDMI DisplayPort PCI-E Video Card
Crucial m4 is a great drive, intel is better but also way more expensive.
Crucial M4 2.5in SATA III Solid State Drive, 128GB at Memory Express
Comes to about $1120 before tax, the extra room you can use for your monitor... Don't forget you can price match at futureshop too I can't find that monitor on futureshop's website but other online dealers have it for ~$250
Edit: You could go for a cheaper mobo but that one is in a pretty god price/performance range.
